Guys like Yakwe and Ahmed have the athleticism to play great defense. They haven't yet, but they could. I think our best line up might be LoVett, Ponds, Ellison, Ahmed and Yakwe. Right now, Sima doesn't move at the speed we need him, too. He's been a liability against just about every player he's up against. Yakwe isn't much better, but at least he has the physical tools.
