Now that's playing to the faithful. You'll never make enemies at a NASCAR track by busting on Kyle Busch.
So what set Jet Ski off? This little move Friday night:
Through the first half of Sunday night's race, Keselowski and Busch didn't have any encounters -- but that's only because Busch was running up front for most of the night, and Keselowski wasn't anywhere near him.
Good rivalry, good show, and exactly what NASCAR needs right now.
