The way I see it:
1) Lebron James
2) Carmelo Anthony
3) LaMarcus Aldridge
4) Jimmy Butler
5) DeMarcus Cousins
6) Steph Curry
7) Anthony Davis
8) Kevin Durant
9) Draymond Green
10) James Harden
11) Kyrie Irving
12) Kawhi Leonard
13) Chris Paul
14) Klay Thompson
15) Russell Westbrook
That leads to this:
PG: Chris Paul, Russell Westbrook, Steph Curry, Kyrie Irving
SG: Jimmy Butler, James Harden, Klay Thompson
SF: Lebron James, Kevin Durant, Kawhi Leonard, Carmelo Anthony
PF: Anthony Davis, Draymond Green, LaMarcus Aldridge
C: DeMarcus Cousins
Russ, Steph, and Kawhi can all play both guard positions. Shooting guard position is pretty self explanatory. Lebron and Carmelo can both play power forward/ And Anthony Davis and Draymond Green can also play center. I think we only need one center, and my bet is that is Boogie, because a lot of the international teams play small.
The first group out is Andre Drummond, Paul George, and Blake Griffin. Frankly, the reason I wouldn't include them is we have players already on the team that do it better. Fortunately, many of the guys won't end up playing. I wouldn't be surprised to see half of my fifteen decide not to play, and that opens the door for a bunch of these other guys.
