Whatever your stance on marijuana is irrelevant. These players know what's prohibited and what's not. It can be hot chocolate that's on the banned list. If your employer is paying you a 7 figure salary, and requesting you to not indulge in something that is of not importance, then you're beyond foolish to perpetually defy them. He's not coming to the Giants.
I love how everyone thinks they know who we will take and who we won't. How many giants had some trouble in their pasts? I can name a bunch. If the player is good enough to make JRs radar and he thinks they are worth a risk and can put the past behind them, then who's to say we don't snatch them up. That said, I like the badger, but agree he's not our typical prospect. I can see us grabbing someone like ogletree though even if he's had some trouble too.
Coughlin had been very public about the troubles of Bradshaw, Hosley and Marvin Austin at the moment they were drafted. They won't take a player unless they believed their issues were long behind them. I don't see how one can say that definitively about Mattieu, especially when talking about a third rounder.
Regardless, he doesn't make much sense outside of a subpackage player and return man.
He failed 10 drug tests ? Maybe JR can put Him in the Scared Straight program lol
