Well you're talking about depth and mentioning other underweight freshmen plus a guy extremely on the opposite end, overweight. So why not mention him?
Of course he needs to get bigger. They all do. Both Jimenez and Nwigwe are fairly slim.

Is having a full 2-deep not better than having nearly every starter and backup interchangeable because of a lack of depth?

I think "if he's ready" is the key question to him and probably 4 other guys as well. I don't know if Hoyt is any less ready than the others. That's why I'm asking. Is he home? How long? Anyone heard anything on his size?
