Why he’s on the list: Dale Earnhardt Jr. wins big on the family name but not at the same level of his father when it comes to the elusive Sprint Cup Championship. (Dale Earnhardt won seven back when it was called the Winston Cup Series.) He had four top-five finishes last season but hasn’t had a win since the Subway Jalapeño 250 in 2010.
