LeSean McCoy has played 11 NFL seasons with three different teams and just won a Super Bowl with the Kansas City Chiefs.
But the veteran running back had never played with a six-time Super Bowl champion before hitting the Tampa Bay Buccaneers' practice field with Tom Brady on Tuesday.
Needless to say, McCoy found out pretty quickly what separates the former New England Patriots quarterback from his peers.

"I've scrimmaged Tom in the past. We're pretty cool," McCoy told reporters Tuesday after officially signing with the Bucs earlier in the day. " ... But to actually see him work, I mean, he's like a general leading the troops, teaching them what he wants in the routes, things like that."
Brady threw passes to McCoy, tight end Rob Gronkowski, wide receiver Mike Evans and other Bucs skill players during Tuesday's session. According to McCoy, the 43-year-old QB turned some heads on the practice field with his high level of play.
"He looked real good," McCoy said. "As he was throwing the ball, I heard a couple of guys whisper, 'Dang, how many years do you think he'll play?' That's how good he looked. Seriously."
While we shouldn't put too much stock in a throwing session without defenders, McCoy also seemed impressed by how Brady carried himself.
"Me and Gronk talked about it: His will to win, his will to go out there and keep doing it -- once you see a guy like that display that attitude, you want to be a part of it," McCoy said. "He looked good today, in good shape. Threw the ball very well. He's like a coach with a helmet on."
That assessment shouldn't surprise Patriots fans who saw Brady lead New England to nine Super Bowl appearances over 20 seasons. It's also a big reason why McCoy says he's in Tampa Bay despite considering a reunion with the Philadelphia Eagles earlier this offseason.
"I mean, come on. I'm in Tampa, nice weather, playing with Tom Brady. How can you beat that?"
