Dermonti Dawson? You guys are too young ... These kinds of polls always seem to be skewed to more modern players.
I would say:
1) Webster
2) Stephenson (May have been best ever if not for career ending injury)
3) Langer
4) Otto - He was a classic. Too bad he's been a cripple most of his post-NFL career. Besides, you have to love a guy who was named Otto, played center, and wore "00" as his number! It doesn't get any cooler than that.
Speaking of which, the NFL, with their rules restrictions on numbers has really lost the color of the league that the AFL brought - no 00's, no 21's at QB (John Hadl), no "6" at RB (Warren McVea) .... those were the days!
I think the next time they do a throw back jersey game, they ought to allow a few of the players to wear the jersey numbers of some of the greats from their previous teams.
