It'd be a good thing for him I think and would probably assist him in his life, and be an asset to a club.
I don't think he's a bad person and everyone deserves second or even third chances.
He might not be a "bad" person, but a quick look at the slimy individuals who he willingly chose to associate with over the past decade - even before the gear took over his life - reveals he is someone with extremely poor judgment.
And while I think people deserve second chances, I'm not sure they deserve 8th or 9th ones.
If he can stay on track for 3-5 years and prove he's worthy of trust, then clubs might start looking at him.
