A close look at remaining USA roster

— -- Sixteen players to choose from. Only 12 roster spots to fill. And a mere 10 more days of practices and exhibition games to collect sufficient on-court data to break any ties.

Those are variables Mike Krzyzewski and Jerry Colangelo have to cope with starting Aug. 13 in Chicago, up until they board the Team USA plane bound for Spain on Aug. 23, in choosing the dozen players who will represent the United States at the inaugural FIBA World Cup.

Tuesday's release of John Wall, Bradley Beal and Paul Millsap, in the wake of the devastating compound leg fracture that felled Paul George, is only Phase 1. To get you (and the USA Basketball bosses) ready for the tough choices ahead -- four more cuts on top of the various emotional challenges after what happened to the well-liked George -- we've broken it all down here by position:

POINT GUARD

Derrick Rose
Any lingering doubt about his explosion or his status on this team were eradicated by the end of the first day of practice in Vegas. It's hard now to see Rose as anything other than the starter at the point against Finland in Team USA's first group game in Bilbao on Sept. 30. Especially after the early show he put on in last Friday's night ill-fated intrasquad scrimmage.

Stephen Curry
Look for him to spend plenty of time at shooting guard even though he's listed here with the other 1s. His boundless range, his versatility, his previous experience in this competition ... Curry is a franchise player with this group just like he is in Oakland.

Kyrie Irving
The sight of Irving starting opposite Rose in the intrasquad scrimmage was the latest indication that he's got a spot sewn up. He can't make the impact yet defensively that Wall can make and isn't quite as flammable offensively as a locked-in Damian Lillard, but USA Basketball regards Irving as a big part of this going forward. Hard to see Coach K leaving him home in those circumstances.

On The Bubble

Damian Lillard
It's not inconceivable that Krzyzewski keeps all four of these guys after letting Wall go, especially given Lillard's aforementioned flammability as a shooter. But four lead guards on a roster of 12 could well be one too many. If so, Lillard losing out to Irving -- one of Coach K's longtime faves -- is the safest forecast.

SHOOTING GUARD

James Harden
There were actual plaudits emanating from Sin City about Harden's efforts defensively last week after his (bad segue alert) borderline sinful showing on that end for the Rockets last season. The Beard, mind you, would probably be in the starting lineup against Finland if he doesn't guard a soul for the rest of the month. He's one of the world's greatest scorers and, among this group of Team USA newcomers, one of the trusted vets.

Klay Thompson
With his size and defensive ability, Thompson actually does give Coach K an excellent option at the 2 if he ever did see the need to drop Harden to the bench. Or Thompson could find himself starting at small forward in place of the injured George given the suddenly sizable void at the 3 spot. Either way, Thompson's ability to make an impact at both ends makes it impossible for Krzyzewski to leave him behind.

On The Bubble

Kyle Korver
He won't complain if he doesn't play and he'll make shots to bust zones when Coach K does send him in. Given his ability to log minutes at small forward as well, Korver will probably find his way onto this roster.

SMALL FORWARD

None
Paul George was the only lock here. And his story is too sad to tell again.

On The Bubble

Chandler Parsons
With his multifaceted game and the size to play both forward spots internationally, as well as his respected range, Parsons appears to have the best shot to make the squad among the bubble 3s. But the competition here is fierce, so his defense won't/can't be overlooked.

DeMar DeRozan
A strong showing in Friday's intrasquad scrimmage, combined with George's unfortunate demise, has put DeRaptor in legit contention for a roster spot when he was widely presumed going to be one of the first cuts. Can he keep the fairy tale going?

Gordon Hayward
All the raves Hayward generated during last year's Team USA mini-camp are what made you think he'd get a max offer in 2014 restricted free agency. But the breakout star of Team USA's brief 2013 time together hasn't been able to generate quite the same buzz as part of this crowd. Small forward is a position in the spotlight over the next two weeks after what happened to the face of the Pacers ... and Hayward has to deliver if he wants to trump DeRozan.

POWER FORWARD

Kevin Durant
Seriously? You're looking for a justification sentence?

Kenneth Faried
Millsap's early exit would seem to suggest that Faried has already won a roster spot. The fact he started opposite Durant in the intrasquad scrimmage was yet another signal the Nuggets' ever-busy 4 man has taken advantage of the July withdrawals of Kevin Love and Blake Griffin. Faried doesn't have the bulk or defensive resume to worry Spain or Brazil ... but his high energy and constant activity will be seen as a nuisance to all who have to deal with it.

CENTER

Anthony Davis
The 12th man on the gold-medal winning London Olympics squad might be the most important player on this team given the limited center options at Coach K's disposal. The Yanks need him to be dominant defensively while also staying out of foul trouble. Which is always an issue for big men in the five-fouls-and-you're-out world of FIBA competition.

On The Bubble

DeMarcus Cousins
Talent isn't the issue. Obviously. Team USA coaches and officials want to bring Boogie abroad with them -- if only to know they can throw him at the Gasol Brothers in the Sept. 14 title game if necessary -- but they need to know first that Cousins can keep his composure and handle limited minutes when his services aren't required. That's what they'll be trying to determine from Aug. 13-22.

Mason Plumlee
Coach K dropped more than a few hints in Vegas last week that the former Blue Devil could actually beat Cousins out for a roster spot thanks to his speed and agility (and presumed willingness to stay hushed if he's parked at the end of the bench). The fact he outplayed Cousins head-to-head in their only shift against each other in Vegas only adds to the notion that Boogie versus Plumlee is the most intriguing battle leading into the real thing.

Andre Drummond
When Team USA practices resume in Chicago, Drummond will indeed find himself needing to play catch up to both Cousins and Plumlee. Coach K is likely to take only two extra centers behind Davis and Drummond, for all his rebounding gifts at a mere 20, is a distinct No. 3 in that race so far after a lackluster week in Vegas.
