we'd get to the playoffs and possibly to the second round. ImShak had some good points regarding what the team would be like going into the playoffs. thing is, we'd probably still have Doc so KO's season would never be.
once Rondo returned, the guard rotation of Rondo, AB, Lee, Crawford and Pressey would have been pretty solid against just about any other team in the East.
PP and Green at SF would be solid.
Frontcourt of Sully, Bass, KG and Fav would have had major issues. KO would not get time under Doc. No real proven center to eat up minutes and allow KG to cut his minutes back. Also, KG seems to have dropped off a cliff this year in terms of offensive performance. Team's D has been in decline since Thibs left, this year would have seen a bigger decline independent of KG's individual decline.
C's would have had enough talent to take out anyone besides the Heat and Indy but not a guarantee that they could. With Indy's implosion, they may have gotten past them as well. There would be enough depth to throw at Wade and Lebron but Bosh would have a field day against that line-up of bigs.
