I'd say given what Monty has done with this team and the team he had last year he's a very good coach IMO. Though I understand people not quite accepting my opinion given most people have probably seen less than a handful of hornets games this season. I can't think of many coaches that could have done better in this situation and kept their team playing with such energy and determination despite the circumstances.
I haven't necessarily sen him out coach anyone though. He's gotten hustle/defensive players to play hard, and i'm sure that locker room is a mess to boot. But ... i don't know, i think i need to see a winning post season run from him before i can say he's that good.
He's certainly far, very far, from being a bad coach.
There's only 5 genuinely very good coaches around that i can think of.
Pop. then a massive gap to doc, thibs, gentry, karl. (maybe add adelman)
Then there's a group that i don't think are necessarily bad, but more flawed than the above, spo, woodson, hollins.
Then you have, i'm not really sure how bad these guys really are, but they've always had talent, scott brooks and mike brown. But you're pretty sure they're flat out bad.
Then you have the erratic ones that are so far between their peaks and troughs, collins, carlisle, Mark jackson ( though he may be in the former), skiles
Then you have the "i think these guys are only care takers until a better coach comes along when the right pieces come together, but at the moment, they're doing a surprisingly ok job" guys, Tyrone Corbin, Frank Vogel (even though he runs the ugliest offense in the league).
I'm not sure where Monty fits into that, i think in that last group. But he'll get another season at least with the hornets before its all said and done, to prove where he belongs.
