I have no expectations of him, but I would be pretty annoyed if the front office kept him on the roster this long only to release him when he is finally able to play again, I know he didn't count against cap or anything but still.
It's not like he's some terrible Greg Hardy type of person beating his girlfriend, this is weed we're talking about. Give him a chance, we have absolutely nothing to lose here.
There really is no negative here for Dallas.
Another failed test, oh well, he hasn't been around anyway.
He just can't make an impact (even as depth), oh well, he hasn't been around anyway.
BUT, if he's serious, if he's clean, if he can provide depth, it's a positive b/c he is still relatively cheap.
AND if he does finally get his head & body together, he'd be a RFA after this year, so there could be value.
