Honestly i can't even understand why discussing him is relevant at this point...
Seriously?
When he was unsigned and un employed I can maybe understand that. But now?
He has a golden opportunity in front of him to supplant a gimpy, injury prone starting RB in Andre Ellington, and at the very least compete for some serious playing time on an offense looking for play makers.
He was signed for a reason. They are not convinced their current stable is enough. No risk look at a former All-Pro who still has some game left in the tank. It's a story right now and if he does well in his pre-season opportunities.....it will be an even bigger story.
If he does not it will fade like a fart in the wind.
