You're right that we can't afford to do so, but Hewitt obviously wasn't happy with the way Sherrod played against Oklahoma given that he was on the bench at the end (unless it was an injury). Maybe it would send an even bigger message to not start him in Haawii, because Sherrod needs to realize we can't win a game in which he only scores 7 points.
Personally I'd like to see the team stop trying to put Sherrod in the limelight and move Allen in there instead. Sherrod clearly doesn't thrive in a leadership role and played his best basketball when he could take a back seat to someone else on the team. Kid has great talent but I don't think he should be the 'face' of the team, if that makes sense. He'll still lead in points I'm just not sure if he wants all the pressure.
