I would not mind a shoot first PG if he made his shots. No, I would not mind Nash one bit. But with all due respect, bringing Nash into the conversation simply highlights how much better of a PG Nash is...both in shooting and playmaking.
The problem with Tinsley is less his attitude and health. It's that his strength is supposed to be on offense...because he is a poor defender. But, he is not only a bad defender, but a poor offensive player with a below avg fg% and below avg in assists as a starting PG.
