His problem was the idiotic Braden Walker character who wears a singlet. If Vince wouldn't always have to be high and mighty we might get to enjoy some people we've seen for years in other promotions. But he has to own the name so we can't.
As "Wildcat" Chris Harris he could have gotten over. I think it would have worked better on Smackdown than ECW due to the larger audience. Many people are people to know he is if he looks like the guy that left TNA.
I expect he'll return to TNA now and eventually be back in the main event scene along with his former AMW partner James Storm.
If he does, I don't expect them to even cross paths right away, but before long they will and maybe even reform the team briefly at some point. Hopefully we don't get another six month feud with them in straight gimmick matches though.
