I may regret this but ...
Patrick look at it this way (I'll use your Wilkerson example). Wilk is 181 points behind Hagan. In 3 races there is a total of 300 points available (not including Nat'l records or qualifying bonuses). Reality is that Wilkerson would have to earn 182 more points than Hagan if Hagan doesn't earn another point from today on. So, that means for every round Hagan wins ... Wilk has to win 2 rounds just gain 20 points. Can Wilk win all 3 remaining races? Sure, he's done that before. But that alone won't put him in the lead.
Mike Dunn is not discrediting those drivers below the line but anything over 100 points is really impossible unless all the teams in front of them fell completely off the face of the earth. Trust me ... Hagan, Neff, Cruz, and Beckman in FC and Massey, Brown and Worsham in TF will all earn some more points and some combination of them will go rounds on Sunday. That just makes it that much more difficult to overcome a triple digit deficit. Mathematically done, NO ... theoretically, YES.
BTW ... you do not still want to give GA a chance in PS Car do you? Since both those cars will always be around late on race day, can we agree that Jason Line is the 2011 PS Champ?
