Brad Keselowski and Jimmie Johnson battled down to the final race in last year’s championship struggle. It looks like more of the same in 2013. The NASCAR Sprint Cup champions battled side by side for the victory in the closing laps at Daytona and Phoenix. Four-time Las Vegas winner Johnson is the standings leader with 2012 champion Keselowski eight points back tied for second. Seven of last year’s Chase qualifiers rank among the top 10 after two races.
