Antonio Brown is known for his questionable behavior and his me-first attitude, but after his whole situation with the Pittsburgh Steelers, you would think that maybe he would have changed.

That doesn't appear to be the case.

When Brown was first introduced as a member of the Oakland Raiders back on March 13, he said that a big goal of his was to catch all-time great receiver Jerry Rice.

And that's fine.

But on Friday, Brown took it a step further by taking to Instagram stories to say that “nothing even matters anymore” other than catching Rice, per Dejan Kovacevic of DK Pittsburgh Sports.

It seems pretty safe to say that Jon Gruden probably didn't like hearing that.

So, apparently, Brown doesn't care about his teammates in Oakland, nor does he care about bringing the Raiders back to prominence. His only concern is topping Rice—a former Raiders receiver, ironically—in stats.

The chances of Brown catching Rice in any of receptions, receiving yards or receiving touchdowns seem very slim at this point, as Rice is miles ahead of Brown in all three categories, and Brown will be 31 years old at the start of the 2019 campaign.

Basically, Brown would need to continue dominating the league for another 10 years to have a realistic shot at catching Rice, and that just does not seem all that probable.

Brown is coming off of a 2018 season in which he hauled in 104 receptions for 1,297 yards and a league-leading 15 touchdowns en route to his sixth straight Pro Bowl appearance.
