What do Tiger Woods and Lebron James have to do with the NFL?
I've recently seen a list of the top NFL players as far as endorsements go and the guys at the top of the list were Peyton, Brady, Brees, Wilson, and Rodgers.
Of those top 5 guys, 1 has a celebration - Aaron Rodgers. It's him quickly putting on a title belt. It's relatively quick. Not real over the top as far as celebrations go. And I've heard him say the whole reason behind it was he started doing it in practice when Favre was the QB and he was on the scout team. And he did it to get the scout team motivated to practice harder. So it actually had a positive team first reason behind it. Something he was doing long before he was a starting QB. Doing it on the practice field where no one but his teammates saw it.
So the top 5 guys get endorsements because of their athletic accomplishments. Not their celebrations.
Actually you make the same point with Tiger and Lebron even though they have nothing to do with football. They get endorsements because of their athletic talent. They don't need theatrics.
If celebrations mattered, the top guys in terms of endorsements would be WWE superstars. Unfortunately they aren't.
