Hall is doing the best with what he's got... The problem isn't him. Fire him and out in anyone else and the results wouldn't be much different, maybe worse. The problem is Kendrick, period...
As for TLR and Stew, one of them should be on the hot seat and it ain't Tony. I would let them both remain until the trade deadline next season. By then, our injured players will have been back long enough to give a definitive indication as to whether or now this team is moving in a positive or negative direction... And if it's negative, Stew needs to go.
