As a Browns fan, I'm neither happy nor up in arms about signing Hunt. With Nick Chubb and Duke Johnson in the backfield, we don't need him and I don't think he'll ever see the field. This is either an altruistic move by Dorsey, who has a prior relationship with Hunt, or a strategic one with an eye toward trading him for a lot more than they're paying for him. I'm also not one who thinks a crime should be held against someone for life as long as he's paid his debt and doesn't repeat the behavior.
As far as Kap, it's simple at this point. There isn't a team that thinks he can help them get better. The "distraction" issue, right or wrong, has blown over but, as you said, his atrophied skills make him less than a viable option. No one in the NFL is going to lose on purpose just to make a point. If he could play, he'd be playing.
