How the Celtics could win it all or come up short

The Celtics will win it all if their core is healthy for the playoffs and no one slips, even just a bit. Keep in mind, their core is the Big Three and they are all past the big 3-0. KG is 32 and has played more than 1,000 career games, all at his ridiculously high intensity level. I don't care who you are, but eventually it burns you out. He never takes a minute off when he's on the court. Pierce is a 31 year old wingman, and as with all wingmen, they rely on a good first step to get to the basket. If he loses that, he turns into a jump shooter, and while Pierce is a good one, the Celtics need him to be a slasher, a creator and a finisher. Ray Allen is 33 with a history of injuries. Of the three, he can most afford to lose a step since his game is less slashing and more spot up shooting. So far, it doesn't look like any of them have slipped at all. It's entirely possible that KG just simply will not let them take a play off.
