I just do not buy that this has anything to do with giving Hunt a second chance. To me, that is a parallel to believing LeBron came back to Cleveland mainly because it was home, and not the talent on the roster.
The only risk of signing Hunt is him screwing up and not adding anything to your roster. The potential benefit, though, because of his talent, is much higher. The Browns do not give a shit about giving him a second chance.
I totally agree that Hunt should be allowed to play in the NFL... but he should have to earn that right, and at this point, he has not done anything other than sit on his ass after the Chiefs cut him. He has not gone to counseling, not effectively addressed the incident, nothing.
The Browns are doing this to improve the team. Hunt has not earned a second chance and the Browns do not care.
I will root for Hunt to do good things for the Browns because I root for the Browns. But, until Hunt actually starts addressing how quickly he escalates to violence, I will not root for or support him in any way.
