These five active players are carrying the team.
1. Vince Carter
2. Stephen Curry
3. Derrick Rose
4. Ricky Rubio
5. Dwyane Wade
Curry would be the starting PG, Wade the starting SG, and Carter the starting SF. Good starting line-up, and the shooting and scoring could be good/great. However the bigs would be average, so my top five would need to be consistent on defense. Also Carter is 40, so he's gonna be preserving himself to play solid. Wade would provide penetration for Curry and Carter.
Rubio would be the back-up PG, and Rose would be the SG, for the most part anyway. Considering outside my favorite current players are average, Rubio could be huge because of his passing. Rose's speed and athleticism could work well with Rubio's passing. Rose also would provide a lot of penetration, which could also be great if when he's on the floor with Curry and Carter.
How many wins would this team have? Tough. Those five players are very talented and experienced, but only one is a SF. Also there's the age and health thing. I think Curry would lead this team to at least 30+, but I don't know.
