This seems overstated. I watch all Celtics games - including the one last night - and just because two guys have slightly differing opinions doesn't mean they are bickering. Honestly this is the first I've heard of it.
I really thought the OP was referring to segment where Mannix got a lot of info from the coaching staff during a break and Scal said he barely gets anybody to talk to him. To which Mannix replied that Scal was too busy coaching them. Although, I suppose this is just adding fuel to the fire
Anyway, until we hear about a real feud, I will continue to enjoy the game cast. Seriously, who do people want over Scal anyway? Do you remember the Donny Marshall days? Bill Walton is awesome, but he is getting older himself. Scal is great imo!
