Hopefully they could Bring Randy back and make him the veteran coach. How perfect would that be? the LHW and HW champs coaching. Kinda like season two only exponentially better.
My one concern would be what is the cut off point for the accomplished fighters vs the younger ones? Are we talking already contracted fighters who jsut haven't caught that buzz vs guys like Tito and Chuck? because that could a potentially horrible situation if one of them loses. I would make the accomplished fighters all previous TUF contestants. Let's say: Forrest is the coach; Bonnar, Jardine, Rashad, Nate, Diego, J-Kosch, Lutter, and Bisping (assuming he makes mw).
I know Joe Silva said they would never use HWs again, so that's pretty much out.
It's better to use all the weight classes, to develop some new talent/personalities in it.
