It's common knowledge that Pittsburgh Steelers wide receiver Mike Wallace(notes) is one of the league's fastest men, and that's not just track speed. Wallace ran a 4.28 40-yard dash at the 2009 scouting combine and has been times as low as 4.22, and he currently ranks second in the league behind Philly's DeSean Jackson(notes) with an average of 20.21 yards per reception.
When the Steelers beat up on the Carolina Panthers last Thursday night to a 27-3 final, Wallace ran past the entire Carolina defense (which is a pretty good defense, even though the team's 2-13 record may not reflect it) for a 43-yard touchdown in the second quarter. The play typified everything that has made Wallace such a dangerous NFL receiver: the initial burst, the extra gear in the open field, and even the little added style point for passing the ball over the goal post.
Wallace experienced Warning Track Fail in Pittsburgh's Heinz Field. He wasn't injured, but he may have been a bit embarrassed. Sometimes you get the warning track, and sometimes, the warning track gets you.
