I don't hate doc but I dislike the way he has handled some situations within the organization.
1) Rajon Rondo (all the coddling while at the same time ignoring the sad reality of Rondo's game as a poor FT shooter and medium-long distance shotting skills).
2) the very poor rotations he uses during regular season and playoffs. I mean, give the veterans MORE rest. Let the younger players earn game experience and let the old legs rest. That alone probably would have helped us dispatch MIA in the last two series we had against them when we ran out of gas.
3) does't like to nurture younger players. If he wants to coach a veteran team, that is fine, but the celtics obviously have needed someone to develop the younger players and Doc just hasn't been that person...
And there's more, there's always more. No coach in the NBA is perfect, but heck, when you see coaches like Carlisle, Popovich or even Spoelstra in recent times, you gotta truly wonder about what Doc supposedly brings to this team that is so unique and irreplaceable.
My two cents.
