As Kevin Harvick and Jimmie Johnson showed Sunday at Chicagoland Speedway, emotions run high in NASCAR when drivers tangle on the track.
And let's be honest about it: Emotions and spirited rivalries are what makes this sport so compelling.
One of our favorite confrontations happened at Auto Club Speedway a couple of years ago, when Joey Logano and Tony Stewart had some serious differences of opinion at the end of a race.
Who can ever forget the interview between Stewart and our dear, departed former colleague, the late, great Steve Byrnes? This really was must-see TV.
