He sucks at football. Like actually.

Right? That's the funniest part, too! He wants to strong arm (no pun intended) some team into signing him to a fat contract for a couple of years so that he stays in the headlines (in his mind) and doesn't fall into obscurity.

What an idiot!

the nfl isn’t slavery, he didn’t say that
