Just doesn't make sense to do something stupid like that. Especially when you have to win games in order to save your job.
Why not? Pitino insisted on using two players to get the ball safely up the court because neither one of them was a good enough ball handler to trust against defensive pressure instead of giving Isaiah Washington any playing time at all in the latter part of his soph year. Washington had his flaws but he was clearly the team's best ball handler. It's telling that when Pitino finally put him in games at the end of the season, he felt no need to provide another player to assist him in that task.
Pitino was a stubborn jerk.
