Other than the previous context provided, I think it's important for people to understand why Antonio Brown is remembered/cared about by NFL fans even if he is an absolute lolcow retard. The upcoming court case will prob make OJ's seem like teeball, so it's best to be prepared.
In 2015, he had peaked in his career with the Pittsburg Steelers.
This is top 5 list of single-season receiving yards as well as single-season receptions in the history of the football.
His single game totals as a WR are also in the top ten in the all-time list.
While this season was overshadowed by Julio Jones in 2015 statistically, he pretty much had one of the greatest seasons of all time at his position.
Unlike the Falcons at the time (only recently competitive during that period and with little history), he was on the Steelers (perpetually competing team for 10+ years with a historic fanbase).
Naturally, he received a shit-ton of publicity and was a part of the shit-ton of ads which are usually targeted to NFL fans during games.
Pizza Hut, Campbell Soups, ESPN, Madden, Pepsi, etc. You can find some online, but a lot of companies have scrubbed them off obviously.
My favorite one is this Pepsi one, where he pretends he's a chud.
He even participated in the magical madden curse, where your cousins, nephews, or sons played with his glowing smile on the cover.
He's batshit insane now, but there was a time when he was basically a super-familiar face in the league, being talked about 24/7 while running ads around the clock.
For people who are white, it's like if Kyle Busch and the M&M car got into a huge crash and went full retard.
The replacement car was sponsored by Skittles, and Kyle Busch would just crash his car into the pit-crew instead of yelling explicatives at them.
His post-career interviews is him talking about being attracted to the green M&M during his prime driving stints.
