Celtics kind of need a star like Dwight Howard to pair with Rondo.
From my perspective (i'm a bit Bias) Boston would be a better fit for Dwight.
LA will be going into 2012 with a 34 year old former star making 27 Mil, a 32 year old STAR power forward making 19 Mil, then Luke Walton/Steve Blake combining for 10 Mil... you do that math on that.
BOS on the other hand will have 35 year old Paul Pierce making 16 Mil, 26 year old Rondo at only 11 Mil then.... wait for it... Avery Bradley making 1.6 Mil (not even guaransheed). Obviously Boston would most likely bring back KG and Ray for much less that what they're currently making (31 Mil combined). Most likely factor in Jeff Green as well.... but you're still looking at around 39 guaranteed money (without Ray and Kevin) and the rest available for Dwight.
Compare that 39 Mil (Rondo, Pierce, Green, Bradley) to 57 Mil (Kobe, Gasol, Walton, Blake)
Oh and by the way... would you rather be coached by Doc Rivers or Brian Shaw?
There's my pitch.
