I actually posted something about this on CSR's facebook page. I can't believe that Buff was talking shit about Jay Lethal's program with Flair. In my opinion, Lethal shined brighter than he ever had with that angle, and Buff just sounded soooo ignorant bashing him.
Tommy Dreamer put it best in his promo on Impact this past Thursday: What Flair did for Lethal is comparable to what Terry Funk did for the ECW guys while he was there. Flair is doing what's best for the company, not what's best for Flair. I applaud him for that, he did such a great job playing "bad-guy wrestler" for Lethal. At the same time, Lethal did a fantastic job in his role as well.
Does anyone remember the promo that Buff did with Piper in WCW? It was around the time that Russo had first arrived, and the whole "new blood rising" angle was starting. From what I remember reading on the dirt-sheets at the time, Piper was supposed to cut all the young guys down, and Buff was supposed to come out to confront him. Buff could have had a main-event turn that night, and I think that was the intended effect. Instead, Buff *****ed out and gave one of the worst interviews I've ever seen. The guy sucked in the ring, and sucked on the mic. He had plenty of time during his WCW run to improve, but he never did.
In my opinion, Buff had the same opportunity back then that Lethal had recently in TNA. Buff couldn't cut the mustard then, and he wouldn't be able to cut it now. I think the reason that he was fired from WWE was because he was just a "body". I mean, girls screamed for him (even when he was a bad guy with WCW), but he could never do anything as a singles-wrestler. He always needed a tag-team partner to make him relevant. That's why he was paired with Scott Norton, Scott Steiner, etc.
Buff sounds delusional in that interview. At one point during that interview he was comparing himself to John Cena and Hulk Hogan? What the fuck? Bagwell even said that he would get "mobbed" if he went shopping at Walmart. I honestly think more people would know who Jay Lethal is than Buff Bagwell in this day and age. The nineties are over, Buff...no one knows who you are anymore, and no one cares that much about you either. I don't think many people would mark out if you made a return to either of the "big two" wrestling companies. I think the announcers would have to do a fair amount of reminding the audience of who the fuck you are.
Buff had a good look, and that's about it. So to answer your question, I don't think he ever would have had any success as a singles wrestler. The guy was a tag-teamer for life, and he wasn't even that great in that role.
