So, Barry Bonds, Roger Clemens, Andy Pettite, Manny Ramirez, A-Rod and many others who used illegal (or at least banned drugs) which could have cost them millions if caught are all mentally weak. Many other athletes have been caught with pot and I dont think I would call them mentally weak, maybe not the brightest people out there but a lot of players are not super smart. I am not condoning pot use in any way but is Michael Phelps mentally weak because he made a mistake like that? Jeffress has serious control problems right now but it is early and AA is usually the rough level for young pitching.
