Charley Hennigan went undrafted in both in the NFL and AFL, but the Houston Oilers of the latter gave him a chance, and aren't they glad they did!

Dick Barwegan was an outstanding Pro Football player, but other than those who decided who should be on the 1950's All-Decade Team; he might be one of the most under the radar players in the history of the game.

We have to way back for this one as Al Nesser played in the NFL from 1920 to 1931, and predated that before the NFL formed with a decade in the long-defunct Ohio League.  Nesser was one of six brothers who played pro football, and he was the last player in professional football not to wear a helmet.  He was a member of two NFL Championship Teams, the Akron Pros in 1920, and the New York Giants in 1927.

Anyone who plays 225 Games defensively in the National Football League is without question a double-tough competitor, and that is what we have in the run-stuffing Linebacker, Hardy Nickerson.
