I'm all for it. Foley can succeed where Helmsley and Undertaker failed in putting over Punk.
"Right now, I'm walking through this cemetery. Not because I'm sad. Because it inspires me. It's the most motivational place on Earth. Why is that? Because people die. When you accept the fact that your time on this Earth is limited, you'll do whatever it takes to make it count." - Bryan Bowers
Brye, I don't think it will be an awesome match. Far from it.
Foley isn't in his 2000 shape or 2004. Foley hobbles all over the place now.
I can see why they'd want to do this match, to get Punk ready for Rock at RR. But I don't think it'd be anywhere near awesome, unless he takes big bumps. And with his age and his injury past, he shouldn't.
I would hope he's got a couple bumps left in him and he'd be able to dust it all off for one match. But I feel like WWE isn't even in the state to do a Foley type match right now that I'd like to see, so you're probably right.
