I wouldn't mind seeing Lawler vs Cole in a Hair vs Hair match. They said they wanted Cole to start taking bumps and train. Plus, they have been "fueding" for quite some time now. How many wrestling fans do you think would pay to see Cole get his head shaved? I know I would. This could even be turned into a retirement angle for Lawler. It could be his one last match, on the grandest stage of them all.
That's a pretty good idea. It would keep the interest for the match since people would love to watch Cole get pummeled unmercifully, and the hair thing would get that nice, big, end pop.
I personally wouldn't mind seeing Lawler in a WM match. He's been faithful, he's been good at the sporadic moments they've taken him away from the commentary table, and I think it would be worth it to even just see the look on his face after the match was over. The genuine emotion the guy would show would be a great "feel good" moment for Mania.
I think there's a guy besides Cole for a match, though, and am surprised nobody has mentioned it in detail yet, that guy being Alex Riley.
Riley would be a perfect 2nd candidate (behind Cole) for Lawler's WM match. The stage is pretty much set already with his involvement with Miz, and it would work even from the standpoint of Cole with Cole's involvement in the whole thing as well.
Couple of different scenarios would work. Lawler could try to pick a fight with Miz again, and Miz could say he's proven himself against Lawler, he's the champ and doesn't have the time to waste on over the hill has-beens, etc. etc. and just feed him Riley in his place. Miz does that often enough so it would work fine and not need a lot of build.
Second scenario is that Lawler wants Cole in the ring, but the GM announces that it will not be Cole, but a representative of Cole's. Cole goes to Miz, who blows it off and says he can't be bothered with it. Riley pipes up and asks Miz to let him be the one to represent Cole, and you have Riley in the ring w/Cole in his corner. Boom, bam, done.
I think Riley is the better scenario for a couple of different reasons. First, I don't think Cole would be Mania ready by then, even if he worked on taking bumps, and Lawler could get his hands on Cole after the match to appease that part of audience satisfaction anyway. Kind of like when Heenan was pretty much the instigator and annoyance when he was a manager. The face would finally meet, and beat, the member of the Heenan family, and then get his hands on Bobby at the end and the crowd would go nuts. Similar situation here. Lawler gets his moment, Cole gets his comeuppance and takes a couple bumps, Lawler goes out respectfully with a nice retirement ceremony the next night on Raw, everything is covered. Hell, after Cole got his beating, it could even explain him being a genuine part of the ceremony. He could legitimately congratulate King without coming across as a dick, but as a humbled guy who gives Lawler his due.
Second reason would be that Riley needs some more in-ring time anyway. He's really not that bad from what I've seen, and him and Lawler could put on a decent match IMO. He needs the experience, it would give him a nice little boost, Lawler could go over him at Mania without people raising much of an eyebrow, plus I don't see it hurting Riley's position any either.
