JuJu Smith-Schuster caught a pass, heard a whistle and then dropped the ball and put up his fists as if to fight.
Smith-Schuster was joking, his humor providing a needed dose of levity to USC's practice Sunday after scout team linebacker Don Hill tackled and then punched tailback Aca'Cedric Ware, which set off a few moments of pushing, shoving and hollering.
"That was so fun — I love it," Smith-Schuster said. "I love when our boys go at it because they're so competitive."
Smith-Schuster, a sophomore receiver, is among USC's most competitive and emotional players.
