Regardless of what the right way to go is or should be, good job on the WWE finding a way to replace an injured worker into an interesting storyline. The whole 11 year bit and how he performed in that Gauntlet (and then EC) really got a lot of people excited. I don't feel any of this would have worked if he was a previous champion/ regular main eventer. Midcard lovable goof that through the power of storyline and people knowing how to play their roles is now a legitimate title contender for an upcoming show.
As for what they should or shouldn't do, I don't know. I would be cool with him getting that title match at Mania. It's more than likely going to be mid-card to upper mid-card position anyway. But honestly, I didn't predict the Kofi stuff getting over as well as it did. Maybe people start going nuts for R-Truth. Who knows what will capture everyone's imagination or what the best fit against Daniel Bryan is. After all, we're all fickle.
