Unpredictability a blessing and curse for NASCAR's 2013 Chase
10. Jeff Gordon (unranked) -- You could make a case for several drivers landing this final spot in the Power Rankings, including Carl Edwards, who is fourth in the point standings. But Edwards has managed only three top-10s over the past nine races and has finished 18th and 39th in his past two starts. Gordon, meanwhile, has six top-10s in nine races, including two in a row. In terms of momentum, the edge goes to Gordon.
