NFL cornerbacks have arguably the toughest assignment in sports - preventing NFL wide receivers from eating their teams secondary alive. As a Philadelphia Eagles fan, I know this all too well. Larry Fitzgerald waxed the birds for over 150 yards and three touchdowns (all three in an excruciating 1st half).
While Fitz is clearly the best WR in the world, almost every NFL team has a dangerous wideout who wants nothing more than to make the opposing corner want to cry. Imagine being out there on an island, standing across from say...Andre Johnson. Poop your pants yet? These guys live for that challenge.
