I think every thing he said is okay. It does not make him a mess. It doesn't make him not a mess but doesn't change my opinion. Are his knees going to be a mess from here on out is the bigger concern. If he can prove to be healthy and the price is right I think you take that risk. Maybe. I do not know enough about him to know if he is mentally unstable. But if he is you can be sure Morey will sign him believing we can fix that part.
