The guys on PTI seemed to suggest Goodell may give him some leniency due to his potential mental instability. Kind of a weird argument to make (even if they did it more gracefully than I). Nonetheless, I can't see this leading to a huge suspension. Two games tops.
Also, I'd be neglecting my snark duties if I didn't say something along the lines of: "Champaign?? I thought this happened in Dallas!"
While it may make for good television to see football players fucking up on the field because they're high, it won't be good for the fan in the stadium who payed good money to see the team WIN... not be fucked up.
