Here is the roster (some of the deep bench players could rotate)
PG - Westbrook/Felton/Christon
SG - Roberson/Abrines/Ferguson
SF - George/Huestis/Singler
PF - Anthony/Patterson/Grant
C - Adams/Collison/Johnson
Very strong starting 5, but a very weak bench, and I worry about them defensively. Roberson is an elite defender as is George, and Adams is very good against a traditional big, but Anthony and Westbrook will be problems on that end, and Adams is useless against a team like the Warriors (he can't guard Green at all). So in a small ball situation, Patterson is probably in at center and he is a problem defensively as well. Maybe they find something with Grant as a small ball center.
At the end of the day that is a great team, but they aren't all that close to the Warriors either. Though, all it takes is one injury or one exploitable matchup, so they would certainly have about as good a chance as anyone.
