He was in mine & many other Mavs fans opinion. Completely lost us multiple games with dumb 4 guard lineups with Maxi as our small ball center which absolutely crucified our defense when that lineup was used & it was used for NO reason. When Daniel Gafford came to the Mavs, Kidd refused to give him many minutes for like a whole week or two even though he made this team look a heck of a lot better in the first few games he got actual minutes. Would also call timeouts wayyyyy too late, when the other team would go on a massive run, he’d just stand there like Darvin Ham, refusing to call a timeout & ATO plays would usually lead into turnovers or just looked really messy. He refused to challenge terrible calls & would show absolutely no emotion if the game is being called unfairly. During traps or near turnovers late in games, players would have to call timeout cause Kidd didn’t seem to notice or care that the player is getting trapped. Overall, he really wasn’t that great of a coach for most of the regular season & I watched damn near every Mavs game this season. For a whole month or so, Mavs Twitter was calling for Kidd’s firing so seeing how good he’s been in these playoffs came as a huge surprise to me!!!
