What Justin Tucker and Matt Bryant did are completely different. Quit you're whining, Pete. You f'ed up.
I don't see the big deal about it myself.
In one situation, the kicker ran onto the field after the end of the quarter with someone who WAS NOT a football player (guy in suit or something) and got a practice kick in while everyone was standing around.
The other was a guy lined up, ready to snap kick and snapped the ball right after the whistle blew.
Two completely different situations. Apparently there is a rule against bringing non-football players on the field after end of quarters and it's a 15-yard penalty, just not really called.
