KG's knee injury in 2009 potentially cost the Celtics the last 2 Championships considering the way he's been playing now that he's fully recovered this year. The only thing I could see causing the Celtics to lose in the 2009 NBA Playoffs with a Healthy KG would be a weaker bench with no James Posey or equivalent caliber backup SF and no one with height after Perkins and KG. It should be obvious that the C's would've won the 2010 NBA Championship with KG playing the way he is now last year even with Perkins being out in Game 6 and Game 7 of the 2010 NBA Finals. Do you think the C's would've won it all in 2009 with a Healthy KG and be on the verge of a 4-Peat attempt?
