tough call but I think Atlanta. stop JJ or Smith and C's are in pretty good shape especially with Horford out.
Orlando concerns me a bit with DH pounding on KG in the first round. I think BBD would come into the series very motivated and as much as he was dogged here, a hustling BBD is an asset to a team.
I'd least like to see Indy. If at all possible, I'd love to see the C's get 3rd seed to have Indy face the Bulls in the 2nd round. If C's get by Miami in the second round (of course I assume C's win the 1st round no matter what

) I think they'd have a fighter's chance against Indy or Chi in the ECF after those two have a real battle in their matchup.
