Yeah, Barry is his uncle and was named for him (Rotunda married Barry's sister I'm guessing, since he is Blackjacks son in law)
Reigns is the rawest, but I think can go the all the way. Has the look, the size but really really needs to work on the mic skills.
Seth Rollins is probably the most atheletic, so so on the mic thus far, reminds me of the next Jeff Hardy, only better.
Dean Ambrose I think is the most interesting right now ... best on the mic, odd style in the ring. Reminds me a lot of Jake the Snake actually.
I didn't see the pay per view, so I'm not sure if they cheated to win the titles or not.
