Kendrick Perkins came back from a blown ACL last night,  adding to Boston's depth and inside toughness. Granted, the first game back was against Cleveland, but it's a step in the right direction.

Perkins was really playing well when he got hurt in the finals. The Lakers were having some issues with his toughness inside. I think the Celtics had an excellent chance of beating LA if he did not get hurt. Now, with the Big Four (Rondo has to be included at this point) and Perkins back in the mix, the Celtics will be really tough. I anticipate a Heat/Celtics Eastern Conference finals

I agree, with you, they will definitely be unstoppable this year
