It must be frustrating for him. Losing your top 3 scorers from a season ago, and adding 2 freshman and 2 grad transfers to the mix must be tough. Especially putting all these guys together, with varying experience, and asking them to play the 2-3 zone defense. This defense takes time to learn and perfect.
I maintain, however, that JB is mishandling this team.
Based on what I've seen, my ideal starting 5 would be White/Battle/AW3/Lydon/Coleman. I think they need to put Battle out there and ride him like a horse. He may be the most talented player on the team, and needs to work through his mistakes. I'd start Howard, but split time with Gillon depending on who has the hot hand. Coleman is a token start, as I think TT is our best option at the 5.
The best defensive/rebounding line-up would be Howard/Battle/AW3/Roberson/Lydon, IMO.
