Nothing to do with the celebration. Heck, I think some of them are fun. I also think it's hypocritical that the Lambeau leap is allowed. HOWEVER, it has NOTHING to do with the celebration. It's the fact that he KNOWS he will get a flag, and especially in an NFL where damn near every kickoff is now a touchback, that 15 yards is absolutely huge. If the league said it was illegal to smile after a touchdown, I think we could all agree that is stupid. However, mature WRs wouldn't smile. Stevie would likey tattoo a smile on his ass.
