Skip to 33:44 for the start of the interview.
I remember thinking Nelson did well vs. Atkins. But his own assessment was that Atkins was tough to handle all game long. Just one of several interesting moments, it's worth a watch/listen.
Another (I am still watching): at his heaviest he was 342 during the season. Also apparently the Colts do enforce weight requirements on at least some of their players.
edit: Deon Cain gives the best interviews of all time.
