the ‘why’ is the nfl can’t have this become standard fare. they keep sidelines very tightly regulated and if the guy hopped in to help celebrate the TD it could become a problem. i know they call it the No Fun League but the reality is it’s a slippery slope. just look at how defenses will run to an endzone to celebrate a fumble recovery. maybe it’s not fun, but the nfl has to regulate who can be on the sideline and when and what interactions they can have with the players. maybe the next CBA will allow for specific team employees to do something like this so that everyone can have more fun? hopefully so.
