That point was reached long ago and the coach is too stubborn do change. Tubby did the same thing when Nolen got hurt and he insisted that Hoffarber play PG. But his only alternative was a freshman Maverick, so you can at least sympathize that he was probably screwed either way. This is just pure stubbornness. And the fact that we only have one good shooter on the team is indeed Pitino's fault.
Still sticking with "12-8 minimum"?
He is also being stubborn in not playing Matz more over Curry. Matz was better earlier in the season than Curry is now. Curry is simply not close to 100%. Unfortunately, he's treating Matz much like he treated Elliot when he was a senior and there's a good chance that Matz's confidence and abilities have deteriorated sitting on the bench for all of those games.
