Andre Caldwell hits Panthers with the dab after first down

The Denver Broncos sure didn't seem nervous on their first possession of Super Bowl 50.

The most memorable play of the drive came after a 22-yard grab by Broncos wide receiver Andre Caldwell. 

After the first down, Caldwell did Cam Newton's Superman impersonation and then hit 'em with the dab, the celebration Newton has made famous. 

Caldwell found a soft spot in the defense, and it was upheld despite a holding call going against the Panthers.

By the Broncos scoring on the first drive, it gave the Panthers their first deficit of the postseason.
