I think I'll sit on the fence on this one.
Personally, I don't see the big deal with the Pitbulls. They seem like yet another overrated ECW team to me. But then again this is also their element.
Benoit and Angle, however, aren't completely out of their element. Angle's been in plenty of street fights and Benoit effectively came from ECW. If I were asked now, I'd go for these two.
