I'd change something before that: in the Orlando series, erase the Captain's broom quote... shut your mouth and take care of the Tragic in 4.
Extending that series meant Baby's concussion, Coward elbowing Quisy AND our bigs (KG and Sheed took a beating, leading to Sheed hurting his back and being limited in the Finals) all of that in Game 5. Not to say a little rest would help the Big 3, big time. Have them taken care of job in Game 4 would've meant a lot, a healthier Sheed, healthy Baby and Quisy and less fatigued veterans.
Other than that, I'd have changed Metta World War injuring Ray, who was huge before that injury.
In my mind there's no doubt the Celts sweep the Fakers in that case. No Perk injury, no JO... #19 on its way in 2010-2011.
but... still hurts and it'll hurt until the Celts win 3 or 4 more banners. Then I'd be ready to forget.
Go Celtics!!!
