FLORHAM PARK, N.J. -- Aaron Glenn was known for his electric speed when he was drafted by the New York Jets in 1994 -- 4.39 seconds in the 40-yard dash.

Now, he's 53 years old with gray hair, but Glenn still has plenty of giddy up. And some dance moves, too.

The Jets' first-year coach went viral Sunday for his reaction to a stunning touchdown by Will McDonald IV , who blocked a field goal attempt and returned it 50 yards for a touchdown to put the Jets ahead in an eventual 29-27 loss to the Tampa Bay Buccaneers .

Glenn was so excited that he sprinted down the sideline, maybe 40 yards, before breaking into a celebration -- an arm-raising, shoulder-shimmying strut. NFL head coaches rarely show that kind of emotion on the sideline.
