Yes, the newly named FIBA World Cup of Basketball is a year—and probably a number of injuries—away from tipping off in Spain in 2014. But it's not too early to think about next year's roster, particularly in the light of this Yahoo! Sports piece that reports four-time MVP LeBron James will sit out the 2014 tournament and likely the 2016 Olympics.
This will be the first time since professionals were allowed to compete in the Olympics that defending American gold medalists will take the floor for a world championship. Team USA's worlds squads in 1994, 1998, 2002 and 2010 all featured players different from the gold-medal-winning teams, although in 1998 that was precipitated out of necessity due to the '98-99 lockout.
As such, I have prepared one roster that includes only Durant and Love as holdovers from 2012, plus one that includes other holdovers as well. Positions listed are international positions, which may be different than the positions a player plays in the NBA.
I also take into account some of Coach K's roster proclivities—in particular liking both players who've played under him at Duke and veteran point guards like Jason Kidd (even though he's now a coach) and Chauncey Billups.
