Big Zeke is injured currently with a torn quad muscle (the same injury that kept HHH out for ages a few years ago). He's expected to return around october/november (ironically the same time HHH is expected back).
Well since the momentum he had after being crowned the last ever ECW champ has been lost (they wanted to push him to the main event, hence why they had him as the last champ), I would have him start off on the mid-card, and have him work his way back up. He has the potential to be a decent monster heel, but he'll have to have a mouthpiece if he wants to main event, I don't recall him ever taking to the mic!!
I have also contemplated having him as a tag partner to Shad (who is in FCW at the moment). I think they could work as a monster heel tag team.
