This is not the dumbest move I have seen all year. That was the Washington player who ran on to the field to celebrate a blocked punt before the end of play, resulting in a penalty for too many players on the field. That negated the blocked punt, and cost Washington the game.
Yesterday's idiots were in the Louisville Washington game after Washington failed on a two point conversion leaving the score 35-34 with 9 seconds remaining. Two idiots for Louisville ran around the field and taunted Washington players. The result was TWO unsportsmanlike penalties, and Washington got to try it's onside kick from the Louisville 35. If they had recovered they would have had an easy field goal try to win the game, instead of having to throw a Hail Mary.
These fools could have cost their team the game. How hard is it to wait to celebrate until after the game or play is over.
