No, I don't. During several games last year it was easy to see that Willie and Juan were buddies; Willie would often force a pass to Willie when other shooters were open. While having buddies on the team is good for familiarity, it's not good when one of the buddies is not a good influence, either on or off the court.
Now that Blake is gone, Willie is going to be the focus of the team. He will be counted on to win games. Patillo, while athletic and energetic, does not make good decisions off the court and dare-I-say, on the court as well? Patillo would play great defense one series, then the next one get caught trying to do too much. Offensively, he's one dimensional (though a pretty good FT shooter) and would try to make plays that he was not capable of making, especially if Willie was feeding him the ball. I'm just not sure he bought into the idea of team.
Blake was too much his own man, too talented, and had an enforcer in Taylor to allow Juan to be too disruptive last year. I'm not convinced Willie is mature enough or has the same support network to force Patillo to play within the team most of the time. Now, Willie will have to take on the role of leader and all that the role entails--there can be no favorites when winning is the goal. This will help his maturity and the development of the front line. By conference time, the players should know their roles making for a better team.
In sum, I think Patillo leaving removes a potential cancer from the team. Yes, OU loses his athleticism, but I believe team cohesiveness improves.
