Well, the way I see it, JBL is most likely going to have a feud with Ron Simmons, his old APA partner. The Y2J Vs. JBL may happen at WM24, but probably not before JBL Vs. Ron Simmons.
As to Wolfie's comment, I have to say I agree to a certain degree. Yes, he is out of shape, but JBL has always been large. 6'8, 300+ pounds. Not very many people that can size up to that, though isn't saying much for a guy who was beaten by Rey Mysterio so easily. JBL has always been a good grappler in my memory, which coupled with his size can spell trouble for a lot of people. But that'll only get you halfway. JBL needs to focus on his mat skills. If he improves those, and throws in a few arials here and there, I'd say he's on his way.
