Most improved teams after 2016 NFL draft

— -- It's impossible to judge a team's draft class the day the draft ends, in part because some picks are made with the future rather than immediate impact in mind.

But based on the picks made Thursday through Saturday, which draft classes improved their teams the most heading into the 2016 season? Below, I identify six franchises that saw their rosters get markedly better thanks to the just-completed draft.

Baltimore Ravens

In the first two days of the draft, GM Ozzie Newsome addressed two of his team's three biggest needs with the selections of OT Ronnie Stanley and OLB Kamalei Correa. An outstanding pass-blocker, Stanley can be trusted to protect QB Joe Flacco's blind side from day one. Correa, meanwhile, has the burst and closing speed to be a difference-maker off the edge. Baltimore needed to get younger at pass-rusher because OLBs Terrell Suggs (33 years old) and Elvis Dumervil (32) are showing a little wear.

Newsome really went to work on Day 3, though, nailing the fourth round with five slam-dunk selections. CB Tavon Young, WR Chris Moore, OT Alex Lewis, DT Willie Henry and RB Kenneth Dixon are all underrated prospects who will find a way to contribute in 2016. Moore, in particular, was a steal at No. 107. The 46th-ranked player on our board, Moore averaged 22 yards per catch and should fit right in with an offense that loves to chuck it deep.

Chicago Bears

Last season, Lamarr Houston led the Bears in sacks with just 8.0, so Chicago had to find a way to get faster and more athletic off the edge. Enter No. 9 overall pick Leonard Floyd, whose 4.60 40 at the combine helped him shoot up draft boards. Floyd has the versatility to drop in coverage and a ton of upside as a pass-rusher. Second-round pick Cody Whitehair started 50 of 51 career college games at Kansas State, and his experience is immediately evident when you watch him on film. He's quick to locate stunts and blitzes and is a plug-and-play starter along the interior of the O-line.

A three-down player with underrated athleticism, fourth-rounder Nick Kwiatkoski is the most instinctive linebacker in this class. He should fit nicely with free-agent acquisitions Danny Trevathan and Jerrell Freeman. And DE Jonathan Bullard has the versatility to line up all over the Bears' D-line, with the first-step quickness and motor to make an impact as a rookie.

Houston Texans

The Texans accomplished the first goal of their offseason by signing QB Brock Osweiler in free agency. But they came into the draft needing to get Bill O'Brien some more toys to play with on offense. They accomplished that in the first round by drafting WR Will Fuller. His 4.32 speed and game-breaking ability is the perfect complement to DeAndre Hopkins.

Houston added two more versatile playmakers in the middle rounds -- WR Braxton Miller and RB Tyler Ervin. Miller is still developing as a wide receiver after playing quarterback for the majority of his college career, but that won't stop O'Brien from deploying him in creative ways. Ervin, meanwhile, is tough to wrangle in the open field and has the 4.41 speed to punish defenses for a misstep. Throw in second-round center Nick Martin, who fills a big need and should start right away, and it's clear that the Texans did everything in their power to surround Osweiler with a bevy of talent.

Jacksonville Jaguars

Think about this for a second: The Jaguars managed to come out of this draft with two of the top eight players on my board (CB Jalen Ramsey and OLB Myles Jack) without trading up. That's quite a haul for Gus Bradley, who has seen his defense finish 28th, 26th and 31st in points allowed since arriving in 2013. Ramsey gives Bradley the long, athletic cornerback he has been looking for. Jack, meanwhile, comes with some medical concerns, which is why he fell all the way to pick No. 36. But at that point, he was well worth the risk for a team in need of his speed and athleticism at the second level. If they get four or five healthy seasons out of him, Jack might end up being the biggest steal of this draft. He's  that good.

The Jags didn't stop there, though, as they snagged one of my favorite players in the draft, Notre Dame DT Sheldon Day, in the fourth round. I've heard all the reasons why he won't be successful in the NFL -- short arms, below-average strength -- but once you watch him play, the positives far outweigh the negatives. Day has elite toughness and a motor that never stops running. GM Dave Caldwell also used a sixth-round pick on QB Brandon Allen, whom we gave a fringe third-round grade. He has the mental makeup and intangibles to push for the backup QB job right away.  

Miami Dolphins

Even the most optimistic of Dolphins fans could not have hoped for OT Laremy Tunsil, the No. 2 prospect on our board, to fall all the way to the 13th selection. But Tunsil unexpectedly slid after a video surfaced on his Twitter account right before the draft started that appeared to show him smoking from a bong. Tunsil's talent is such that this was a worthwhile risk for the Dolphins to take at No. 13. He has the highest ceiling of any player in this draft and is the best pass protector we've seen come out in years. He immediately improves an offensive line that has allowed QB Ryan Tannehill to get sacked 149 times the past three seasons, 18 more than any other quarterback.

Third-round RB Kenyan Drake comes with some durability concerns, but when healthy, he's one of the most explosive open-field athletes in this class. While he's not a great between-the-tackles runner, Drake will make his presence felt in the passing game and as a returner. Third-rounder Leonte Carroo gives Tannehill another WR who can go up and get the ball in contested-catch situations. Carroo should compete for playing time with Kenny Stills, who had just 27 catches for 440 yards in 16 games last season. 

Tennessee Titans

Marcus Mariota was sacked 3.17 times per game last season. Only Jaguars QB   Blake Bortles got wrangled more often. The pounding took a toll on the slim-framed Mariota, as he missed four games after spraining both of his MCLs. Clearly, the No. 1 priority   for the Titans heading into the draft was to find an upgrade at offensive tackle. They traded up to No. 8 to select Jack Conklin, who's one of the safest picks in the draft. He can fill in immediately at RT, help keep Mariota upright and make Tennessee a lot tougher in the run game. That's clearly a priority after the Titans traded for DeMarco Murray in the offseason and picked Heisman winner Derrick Henry with one of their three second-round selections.
