No it's not.
I hear alot of Celtics fans bring this up and I just don't think it's true.
Avery Bradley is a good player but he would NOT have made a difference.
I think Miami missing Chris Bosh for games 1-4, and then getting him back at 100% for game 6 and 7 was a MUCH bigger difference maker than Bradley would've been.
Remember, Lebron singlehandledly torched us in game 6 for 45 pts. Bradley doesn't even come close to impacting that.
