Bleacher Report surveyed 62 NFL players, coaches and executives about who they believed were the most unstoppable players around the league. Each person named a top three, starting with first-place votes.
5. A.J. Green (6 first-place votes)
"Best route-runner in the game. I know a lot of people love Odell [Beckham Jr.], but I don't think he's there yet, and you can clearly get in his head right now. The thing about [Green] is that he's so smooth with everything. You can be physical with him because he doesn't like to get touched, but that's about the only thing you can do, and you better be perfect." — NFC cornerback
4. Tom Brady (8)
"Everybody knows the way to stop him. The problem is doing it. You have to get pressure in his face and make him nervous. Simple, right? Yeah, good luck. He gets rid of the ball faster than anyone. He knows what you're trying to do, and he has all those little, quick receivers who run one short pattern after another. Then, when you sell out to take somebody like [Julian] Edelman away, Brady hits [Rob Gronkowski] and shatters your whole defense." — NFC assistant coach
3. Antonio Brown (9)
"He has the best footwork of any receiver in the league, and he's tireless. He runs the same speed in the fourth quarter as he does in the first quarter. His quickness makes it impossible to bump him off the line. But like I said, that dude never stops. I hate playing against him. He never takes a play off." — AFC cornerback
"He's the closest thing I have seen to Marvin Harrison since Marvin was in his heyday. When you played Marvin, you always thought, 'Let's just beat the crap out of him.' Then you spend the whole game trying to catch him. It's like that scene from Rocky when he's chasing the chicken and it keeps getting away from him." — AFC assistant coach
2. Julio Jones (12)
"He's [Terrell Owens] without all the crap to deal with. What route do you want him to run? He's great at all of it. We had a game where we knew he was going to go deep on a certain play. We just knew it. He still kicked our [butt]. Then he ran about a thousand crossing routes on us. He may not run the crispest patterns, but his size and speed overwhelm you anyway." — AFC coach
"He's like the perfect combo of finesse and physical. He wants to run his routes and do everything on time. But when you try to get physical with him, he hammers you. He likes the contact. He just doesn't start it." — NFC safety
1. Rob Gronkowski (15)
"He's more than just a receiving tight end. He wants to beat you every way possible. He wants to run past you. He wants to run over you. He may not be the best blocking tight end, but he likes it enough that he's dangerous. He even likes to talk trash. He wants to embarrass you, and he doesn't back down from anything." — NFC cornerback
"You see the physical part of what he does. That's obvious. But what he does a lot of time is break the spirit of your defense. I can't tell you how many cornerbacks and safeties are literally scared to tackle him because he'll hurt you. So what he does is break your spirit. He gets free, runs through the defense and then your guys are looking at each other like, 'Man, what do you expect me to do?'" — AFC coach
Others receiving first-place votes: Aaron Rodgers (5), Odell Beckham Jr. (3), Le'Veon Bell (1), Tyler Eifert (1), Ezekiel Elliott (1) and Greg Olsen (1).
