There a many players that have played quite a few years that may never have been an elite player. They just played for a very long time. IMO, that does not make them HOFers . . . just guys that played for a very long time.For example, Keenan McCardell played long enough to rank around the top 10 in some important receiving categories by playing for 16 years. Is he really a HOF candidate? Ottis Anderson had several big years out of the gate but didn't do a ton beyond that in his 15 year career . . . should he be in the HOF? Of course, there is Vinny Testaverde who managed to bounce around to 7 teams in 20 years. Sure, he played a long time . . . but a HOF guy?That's where, IMO, there should be a subjective threshold to evaluate how well a player did in his peak and his average per game production. Guys that played in 200 games and averaged 40-50 yards of offense (as a non QB) really didn't do a whole heck of a lot. I'd rather induct a player that accounted for 120 yards of offense a game in 100 games.
