Hamlin not hurt by late-race cautions, Joe Gibbs Racing dominates

NASCAR Power Rankings

Denny Hamlin is unstoppable, debris cautions be damned. The 29-year-old Virginian and NASCAR's greatest hope of stopping Jimmie Johnson's domination of the Sprint Cup, continued his long march through the regular season with a victory at Michigan on Sunday. Hamlin is already the Sprint Cup wins leader with five trips to Victory Lane, but is he limbering up that surgically repaired knee for the Chase or wearing out his lead foot? Have a comment?
