First off, Jerry Rice is a great athlete (and the best on this list). He was picked in the first round of the 1985 NFL Draft and number one on the list of the NFL's greatest players for a reason. But for how good of a player Rice was, his physical prowess didn't measure up.
Rice played defensive back, wide receiver, running back and quarterback in high school, but wasn't a good enough athlete to garner any Division-I scholarship offers. He attended Mississippi Valley State University.
Rice consistently beat the NFL's top cornerbacks, and burned secondaries no matter the coverage schemes. It wasn't because he was faster than his opponents.
He worked extremely hard on every facet of his game. Rice constantly studied the playbook, worked on his route-running, and stayed after practices to perfect his receiving skills.
Through his career, Rice had 1,548 receptions for 22,895 yards and 197 touchdowns. Alongside Joe Montana and Steve Young, Rice won three Super Bowls. He appeared in another with the Oakland Raiders, and Rice is widely consider the best player to ever play the game.
