I agree with you as far as the long term committment to winning goes. But what about those fans paying to see the last 15 or so games in Arco? Do they not deserve to see a quality product? It seems like sort of a conflict to me.
I think we had a quality (watchable) product with Beno and without Bibby. And that is what we will have again for the last 1/3 of the season, whether or not the new guys play. I think Sheldon should get serious PT to see what he can do, the rest can play reserve roles as necessary.
