5-on-5: Is Russell Westbrook a top-50 player of all time?

— -- The All-Time #NBARank continues with players 46-50. Our experts debate Reggie Miller vs. Ray Allen, Russell Westbrook's ranking and more in the latest 5-on-5.

1. Who should rank higher: Ray Allen or Reggie Miller?

Bradford Doolittle, ESPN Insider: Based on regular-season performance, not to mention style, they could hardly be closer. Miller was better at leveraging his outside shooting into getting to the line. Allen had a better handle and could make plays for others. In the end, I go with Miller based on his superior postseason record.

Kevin Pelton, ESPN Insider: As much as it pains me to say it, having covered Allen for four-plus seasons with the Seattle Sonics, I'd lean slightly to Miller. He was the more efficient scorer and also has the edge in terms of longevity -- a strength for both players.

David Thorpe, ESPN Insider: Miller. Usually the top scoring threat on his team, he had fewer open shots. And 3s were a smaller part of the game in his era. An aging Reggie Miller playing next to LeBron James and Dwyane Wade is a fun thought. I might have to get my son an Xbox so we can experiment with that.

Micah Adams, ESPN Stats & Information: While their numbers are strikingly similar, I think that does a disservice to how well-rounded Allen's game was in his prime. Allen averaged four rebounds per game 11 times, something Miller never did. Allen had five seasons in which he averaged more assists per game than Miller's career high. And winning two titles -- while hitting the most iconic series-swinging shot in Finals history -- gives Allen the edge.

2. What is the legacy of Allen Iverson?

Elhassan: Iverson's everlasting legacy is that scorers (namely shooting guards) did not have to be the prototypical 6-feet-4 and taller to flourish in the league. He opened the door for countless other undersized scoring 2 guards, from Ben Gordon to Monta Ellis to Lou Williams, though none have approached his prowess as a scorer. My favorite memory has to be the crossover of Michael Jordan in Iverson's rookie season. It was such a powerful metaphor for the changing of the guard.

Doolittle: I was never a big Iverson guy. Great, unique player. But I tend to look at the NBA through a team-building lens, and his game was troublesome from that perspective. And there was so much offcourt noise with him. Still, I think his legacy is one of toughness, and that's not a bad one to have.

Pelton: My favorite memory is going to see Iverson face the Sonics his rookie season with my brother, who was wearing his Iverson jersey. He tip-dunked home a missed free throw, which remains stunning for any player, let alone one who was 6 feet tall. As far as legacy, Iverson stands as the avatar of his era. Unfortunately, it's not one that's aged well in terms of stars logging huge minutes and the ability to score being valued over efficiency, but Iverson defined it nonetheless.

Thorpe: Iverson's teammates for the 1995 World University Games included Tim Duncan, Ray Allen and eight other future NBA players. I was invited to watch practice by coach Lon Kruger, a mentor of mine.

Iverson had the most energy, every single possession. Guarding Chucky Atkins in half-court scrimmages, Iverson would turn and scream, "Let's play some defense!" Then he defended with every ounce of his body on every possession that weekend. We'd look at each other and smile, knowing we were watching a once-in-a-generation type of player.

Iverson led the team in scoring, assists and steals as it set records on the way to the gold medal.

Adams: The most fearless player I remember. Game 1 of the 2001 NBA Finals was the only time the Lakers lost in that postseason; scoring 48 and showing the audacity to step over Tyronn Lue were Iverson at his best. Plus the Reeboks, the crossovers, the cornrows, the shorts, the swagger -- there isn't a player who had a more profound impact in shaping the modern NBA.

3. Russell Westbrook at No. 49: Ranked too high, too low or just right?

Elhassan: Probably just about right, if we project him to continue at this pace for a few more seasons. Westbrook is unequivocally the greatest athlete we've seen at the point guard position, the pinnacle of human evolution, if you will. He's also improved by leaps and bounds skill-wise during his time in the league. He still hasn't figured the optimal balance between volume and efficiency, and still has room for improvement in the decision-making department. We can't ignore the talent that he is, but he's got to evolve himself in order to move up on the list.

Doolittle: Way, way too high. If you're going to get into the top 50, you've got to have some combination of MVPs, titles and longevity. He's got none of the above. Not saying he can't or won't get there, but let's at least let his prime play out.

Pelton: Too high. Westbrook is getting too much credit too soon. Last season was the first time Westbrook even finished in the top eight in MVP voting, and he's never made an All-NBA first team. Westbrook is well on his way to a top-50 career but he doesn't belong there based on his accomplishments to date.

Thorpe: He's fine right there, because he still has a lot of years left. Perhaps he will get a title or two, perhaps not, but what he is doing on a nightly basis will get him into the top 30 or so regardless. Westbrook is the most athletic point guard ever, taking into account his size and physicality. When combined with an incredibly hot motor that never cools, you have a player we just can't put a ceiling on.

Adams: Probably too high for right now. There's no questioning his talent, but we haven't really seen it translate into enough team success yet. So I don't think he gets the benefit of the doubt of extrapolating too far into the future, unlike someone like Stephen Curry.

4. Which player should have made the top 50?

Elhassan: Aw man, where do I begin? Bob McAdoo was a pioneer as a big man who was an unstoppable scorer from the perimeter. Reggie Miller was the gold standard for 3-point shooting. Dennis Rodman might be the most versatile defensive player in history. Those three names definitely stand out to me.

Doolittle: It's so tempting to say Bernard King (No. 54) but I know I feel that way because he's my all-time favorite player, so I'll let this shout-out serve as a homage. Pau Gasol (No. 56) has a solid case -- he's 35th in career win shares and has two rings. If we include ABA performances (I know, it's #NBArank), Artis Gilmore (No. 70) clearly is top 50.

Pelton:  Dwight Howard. Howard is already 58th in career win shares according to Basketball-Reference.com, and that undersells his impact on his team because most of that value has come in his prime rather than decline years. Howard is also among just 25 players in league history with five All-NBA first team appearances. He'd be a top-50 player if he retired today.

Thorpe: McAdoo and Dave Cowens can make a claim. Each won an MVP, had multiple first team All-NBA selections, won multiple titles and won either multiple scoring titles (McAdoo) or was named to multiple all-defensive teams (Cowens). Not every guy above them did as much. Both were also incredibly rare players for their size.

Adams: Grant Hill. There is a perception that Hill is a case of "what might have been," and that shortchanges his actual career. His first six years stack up with those of players like LeBron and Oscar Robertson: 21 PPG, 7 RPG and 6 APG. He also made an All-Star team in his 10th season, after that supposed prime and after his return from injury.

5. Bill Walton is just outside the top 40. If he had stayed healthy, where would he rank all time?

Elhassan: Whether it's Walton, Arvydas Sabonis, or Grant Hill, there's no greater regret than seeing a once-in-a-generation talent struck down by the injury bug. For Walton, an elite passing big, dominant rebounder, and tremendous rim-protecting presence, it's hard to imagine him falling out of the top 25 if he had been able to continue his career with full health.

Doolittle: He won the MVP in 1977-78 even though his regular season ended in February and, if he hadn't been hurt that season, Portland likely would have won a second straight title. He was just 25 at the time. After all the injuries and missed seasons that followed, he was the NBA Sixth Man of the Year on another title team when he was 33. A healthy Walton is a top 10-15 all-time player.

Pelton: I think it's likely Walton would have won at least one more MVP award, which would have put him among 13 players in NBA history with multiple MVPs. Even with good health, Walton's peak value might have overshadowed his career value since he didn't break through as an NBA star until age 24. I could see a healthy Walton finishing in the latter part of the top 20.

Thorpe: Potentially top 10. Why? Perfect pivot man when most of the league had no clue how to play as he did. Seven-footer with incredible skill and nuances to his game honed by thousands of hours of brilliant drills run by John Wooden and Dr. Jack Ramsay. Perfect teammate on both ends of the court. The rare big man who helped teammates get buckets while also protecting them on the other end.

Adams: Walton would slot somewhere in the mid-20s overall. Great defensively, great basketball IQ, an MVP, made everyone around him better in the same way as Bill Russell. He wasn't as outright dominant as guys like Moses Malone, Shaquille O'Neal, David Robinson and Hakeem Olajuwon.
