Coaches are playing a starring role in the locker-room celebrations that have become a staple of March Madness.

The latest example of this trend comes from Michigan’s John Beilein, who headed into the locker room with a water gun as he greeted his players after the Wolverines’ upset of Louisville.

One day earlier, Wisconsin’s Greg Gard had a water bottle rather than a water gun as he headed into the locker room after the Badgers’ victory over Villanova.

Some  of these festivities have even included coaches from other sports. Northwestern football coach Pat Fitzgerald visited the Wildcats’ locker room after their first-round victory over Vanderbilt.
