Yeah, outside of maybe 5 or 6 guys, I don't think I would be too upset with anyone leaving. Everyone needs to remember how bad we've been lately. Hardly anyone isn't replaceable. I know that sounds bad, but it's the cold hard truth.
Off the top of my head, I wouldn't want to lose Lazard, Warren, Cotton-Moya, maybe Lanning.... not sure who else? I'm sure there are a few others, but I'd have to think about it.
IMO losing Campos, Tucker, Peavy, Tribune, Jordan Harris, and Wesley would sting. They all have Big 12 starting experience at least.
