I'll always be grateful for what he did in leading us to the title in '08.
That being said, I did feel like he got too much of a pass from the fans and media at times here. With all the talent we had, there were so many 5 minute stretches even when the starters were in where we didn't get a single good shot. I realize the coach can't make shots for players, but he can make sure that they're at least taking/creating good shots. That was Doc's biggest flaw as a coach here, IMO.
Not sure we'll ever know all of the details surrounding his exit, as his side of the story and Danny's side of the story vary significantly. If Doc decided that he didn't have the patience/desire to help lead the rebuild, then that's his right, but it doesn't mean I have to root for him elsewhere.
Two playoff games that will haunt Celtics fans for a long time are Game 6 against the Lakers in 2010 when we just didn't show up, and Game 6 at home against the Heat in 2012 when we just didn't show up. Game 7 was a heartbreaker in both series, but we had the momentum and a great opportunity to close out each series in Game 6 but just didn't show up. The head coach deserves some of the blame for that.
While I love the job Stevens has done here thus far, he hasn't proven nearly as much in the playoffs as Doc did. Stevens obviously hasn't had the same roster at his disposal that Doc did, so I don't mean that as a criticism of Stevens. But I also think it's premature to be overly complimentary of the job Stevens has done until we see his team produce in the playoffs.
