re: Who is the most athletic person on a football field at any given time?

Defensive backs. They play a reaction position and have to have the speed to recover, the ball skills of wr's, plus the ability to tackle rb's that are almost always bigger than them.

Antonio and Julio Jones seem like the best athletes in the NFL but alot of DB's can make a case. Earl Thomas, Kam Chancellor, Peterson, Eric Berry, shite you can throw Lattimore from the Saints in there with the kind of rookie yr he's having.

Aaron Donald is an outlier, that guy is an insane athlete
