Brodus Clay hasn't failed - yet. The WWE has a serious problem on their hands with Brodus, if they intend to make him successful. On the one hand, you can book Brodus like a monster heel. That, however, is a problem because we are coming off a summer and fall dominated by Mark Henry and now the main event of Raw being dominated by Kane. A monster heel in the current scene is just white noise that I really have trouble envisioning anyone caring about. On the flip side, his current gimmick is completely unsustainable. Sure, it's nice to come out to a great song, dance around, make everybody laugh, and squash jobbers. But that obviously can't last, which is probably why he hasn't been on TV for two weeks. This is something of a damned if you do, damned if you don't scenario for the WWE, and really why they should have had the good sense to keep Brodus Clay off of television until after WrestleMania if they'd wanted long term success out of the guy. Now, let's be clear, he certainly hasn't failed yet, but I would agree that if all he does is continue in squash matches, he will.
So, the solution here is to salvage the current gimmick, of course. Turning him into a monster heel at this point would be unsound from almost all perspectives. It doesn't make sense in storyline, no one would care about him for the reasons aforementioned, and it would kill the momentum he already has going. The more appropriate venue is for him to actually start a feud and cut some promos. I have no doubt that there's a solid character in the Funkasaurus, they just need to write some material for him and let him come out. Give Brodus a microphone and an opponent that isn't Curt Hawkins. More importantly, let work a long enough match to actually connect with the audience. Swagger is probably the obvious guy to do this right now, and is doubly effective since it can add the title to the mix.
The Funkasaurus can work, it just needs what every new character needs - a program, a feud, an opponent, and all the necessary trappings that go into a successful wrestling character and storyline.
