The funny thing about Nate is that with his size, speed, athleticism and hitting ability, there's a chance that he could have been an awesome safety.
But because cornerbacks get paid more, he had no interest in making the position switch.
Had he made a few Pro Bowls as a safety, there would probably be some interest in his services.
A comparable athlete, Ronnie Lott was wise enough to switch to safety in 1985, his 5th year in the league. Lott ended up playing 15 seasons in the NFL.
