Keselowski didn't qualify for the playoffs this season, but given his mastery of the Chase tracks in 2012, expectations were high for the driver of the No. 2 Dodge. He hasn't delivered. Yes, he did reach Victory Lane at Charlotte in October, but the reigning Cup champ's average finish in the first eight playoff races has been 14.0 -- a far cry from his Chase average of 6.2 from a year ago.
