I will say this. People outside of Steeler fans do not like JuJu. My buddy, who is a comedy writer, and used to write excellent football articles (Quick Inside Slant), stated at our college friend's Christmas party, that he has a new least favorite player in the league. He saw the hit on Burfict as egregious, and the taunting afterward as unacceptable. I agree on the taunting, and chalked it up to immaturity. He is a rookie. Then he reenacts it for a TD celebration. That was classless, and I have no defense for that.
I think he will grow up from these instances, because that is the only thing holding him back from being a fan favorite across the league. Personally, I can see how he got caught up in the moment by laying a huge hit on a player that has knocked all of our Killer Bs from games at one time or another. There is justification to that point of view.
It's just that, thanks to Gruden, JuJu is painted as dirty player outside of our fans.
