Hamilton will trade his rights if they're smart. Jeremiah Masoli looked great down the stretch once he got the ball. They need to bring in someone to push him/plan B type of thing, assuming Collaros gets cut, but a distraction like Manziel is a bad idea. Montreal is seemingly the most likely trading partner.
Manziel has the tools to be decent in the CFL if he has his head on straight and doesn't come in expecting to be a starter right out of the gate. I guess we'll find out if he's grown up yet. I expect he'll at least be in camp somewhere next spring.
