This isn't the best player who ever lived, but when I was at UW I had this ILB i fucking adored named Emmanuel Dunbar who was just this fucking thrasher in the middle of the defense. He had a lot of help with the DL being as good as it was, but i'll be fucking damned if he didn't almost always showed up. His final game was also pretty fucking memorable too.
Won the MVP too. I know I was the only person on this site who will remember this guy, and I am the only one who tends to notice these types of things or enjoys players like this, but he's the one reason I really really wanted XFLHC/AAFHC so he could maybe somehow someway make it to the NFLHC on a practice squad or something. He was so much fun, and easily my favorite unknown never made the NFL player.
