DO had to get in better shape; he would get winded too quickly, which is why he was subbed for often 90 seconds into a game.
Crump and Harris just may never become the players we thought they would be. Crump seemingly hasn't improved on the defensive end at all, and his shot selection is just awful. We need him to take good shots, and we need him to hit them. If he can't do that, he's a liability.
Harris is a shockingly poor ballhandler. There's no reason a 6'4" SG should get the ball stripped away so often or to not be able to hold onto passes. He also needs to hit shots (which he won't if he keeps shooting so flat); if he can't, then he too is a liability.
Hightower flashes brilliance one minute and incompetence the next. He is alarmingly inconsistent as well. But he's only a sophomore in a completely new system that should fit his skills. I will be more patient with him.
It's way too early to rule out improvement for these guys and the team, but these guys must improve for the team to get better.
Like you, Sid, I don't like that final line-up. That won't win us many games.
