Antonio Brown's offseason has definitely been eventful. After getting traded from the Pittsburgh Steelers to the Oakland Raiders, he's faced a lot of scrutiny. Something no one can deny is his talent on the field and his work ethic off of it.

Brown is known for his next-level skills on the field. Therefore, it should come as no surprise that his workouts off the field are the same thing – next level.

Now truthfully, these types of videos come out every year. Different athletes doing ridiculous things. You would think at this point it's old news, right? Wrong.

This just goes to show the ridiculous level of balance and hand-eye coordination these athletes have. Antonio Brown isn't an elite receiver for no reason. He's one of the best because he works hard and does things like this – things that most people couldn't do in a million attempts. And he makes it look easy.

Admittedly, this isn't the most insane workout video you'll ever see. Don't sleep on the difficulty though. Trying to catch multiple tennis balls coming at you like that while continuously stepping up and back like that can't be easy.

I'd like to consider myself not completely useless when it comes to athletic ability. I'm definitely nothing special but I can move around. That being said, I guarantee if I tried this it wouldn't end well for me.

Antonio Brown is just a different beast man.
