'Pinch' otherwise known as Rowdy and Wild Thing to most... is the best overall talent in NASCAR's top-3 series. You are right that he definitely relishes his role, and so do the fans.
As far as predicting a winner on Sunday, I would say look no further than the first three rows of the starting grid. I think one of those six is your 2010 Daytona 500 Champion. However with the truck race being delayed until tomorrow night, I'm not so sure about Busch's chances on Sunday. The kid is an animal but that's a whole lot of racing/ happy hour practice in a 24 hour period. We'll see what he does.
