Orlando made the right call at the time
I thought it was a terrible decision at the time. Doc was doing a solid job on mediocre team. They'd struggled out of the gate, it was a gross overreaction at a terrible time that doomed the rest of their season.
They were, what, 1-10 at the time, the fans hated Doc, and he was losing his team. The team hadn't progressed in three seasons, despite spending a ton of money on free agents. The team desperately needed, as Joe Dumars might say, a "new voice".
It's hard to make progess when your best or second best player is injured and your GM consistently makes bad decisions. As Doc said at the time he had to have two training camps and two different plans every year/game, one for Grant being fit and one for the team without Grant Hill.
Darrell Armstrong should never have been let go, he was the team's leader and a quality point guard. Their GM never even bothered to replace him. Bad draft picks like Reece Gaines. Or maybe it was Curtis Bochardt, Steven Hunter, Jerryl Sasser that were meant to lead to progess. They also allowed Troy Hudson to leave, again unreplaced. Then they trade Tracy's only decent sidekick scoring threat in Mike Miller. The replacement comes next summer, Juwan Howard, a guy who plays the exact same position as the guy they traded Miller for (Gooden). Co-incidently Howard was the only Free Agent they spent serious money on outside of Grant/Tracy for Doc's four years there. Then they fire Doc 11 games into the season without giving him a fair shot of trying to make that work. Then of course they trade Gooden for next to nothing shortly after Doc leaves because the Mike Miller trade didn't work. Add in the assortment of 35+ players like Horace Grant, Shawn Kemp, Patrick Ewing, Rod Strickland who were supposed to be able to contribute. That didn't work either.
Through each year of Doc's final 3 and 1/8 seasons his team's talent levels consistently got worse. Keeping the ship steady was good work.
I hate teams that fire their coaches 10 games into a season. It's never a wise move unless it's completely neccessary and it wasn't in this case. It's even dumber when there's no clear replacement.
Firing Doc Rivers for Johnny Davis at that time was along the lines of firing Dwayne Casey for Randy Wittman. Except Doc got only 11 games and had done more in previous seasons with his team (3 playoff appearances, one just miss, CoY) just to make it a bit worse. I hate it when teams fire their coaches like that, especially when they have no quality replacement available to them.
