Not really. I mean, just listen to his presser. When asked a question he doesn't like, Manning calmly dodges it. When asked about Hudson and Rondale, he only remarks on Hudson. Manning spent 10 years at Kansas and he comes off as a hard-ass who believes the system and the prep is more important than the player. So if you do something stupid he'll plug in VanHorn because fuck you. If the scouting report says don't let player X shoot open 3's and our players keep losing him we're not zoning up because fuck that.
Feel free to think the guy is an idiot who has no idea what he's doing. If you acknowledge that he's has dedicated his entire life to the game of basketball including coaching from the ground floor up, it's pretty hard to buy into the "he has no idea what he's doing, I'm a dentist and even I could coach our substitutions better" reactions after game #3.
