The celtics can still contend next year though....fans on this site seem to have short memories...but granted its understandable with our last memory being beaten by the heat in 5 games...
our "big 3" can still perform at a high level, and as long as we can get some production out of our bench and Rondo/the big 3 are healthy we are still a good team...we were a healthy Rondo/botched last play from tie-ing the Heat series 2-2 and then who knows from there..
Here's the thing, though. The Big 3 may still be able to play at a very high level collectively, and Rondo will almost surely be better throughout most of the season and the playoffs next year than he was toward the end of the regular season and in the playoffs this year.
However, the Big 3 more than ever need young roleplayers to step up and take the load off their shoulders. In particular they need guys who can do dirty work down low in order to open up the offense. I just don't see how the Celtics can put together that kind of a supporting cast this summer.
So unless Rondo comes back playing like he did at the start of the regular season this year and sustains that sort of play throughout the season and into the playoffs while also increasing his scoring, I don't see how the Celtics will realistically contend next season, barring some very fortuitous injuries to the key players of some of the other contenders.
