I'm not sure this is the right move: the Mavericks fired Avery Johnson from their head coaching position following the Mavs' second straight first round playoff exit.
Now I agree that with the Mavs current team, they weren't gonna go any further and a change needed to be made, but I don't think it was Avery's fault. Really, the reason this team failed is because they have Dirk Nowitzki (a very good, but not great player), Josh Howard (who at any given point may be high and has entered Ben Wallace territory in that he's been underrated for so long, he's now overrated), Jason Terry (who can shoot but is too streaky and can't play defense), and the shell of Jason Kidd. Simply put, the team wasn't that good and couldn't defend Chris Paul when it mattered (something I believe only the Spurs or Lakers could do in the west). Johnson had an excellent 194-70 record in the regular season during his tenure. Unfortunately, his 23-24 in the playoffs was his undoing. My only question is "who's next?" I don't see anybody who could be considered significantly better. Rick Carlisle maybe? If Mike D'Antoni is fired then he'd be better, but his teams haven't gotten much further in the playoffs either.
Regardless, tough luck, Avery. But don't worry, you'll have a job somewhere else very soon.
