Frank Gore has played 11 seasons and is 15th all time in rushing with 12,040 yards. 12/14 players in front of him are in the HOF. 2/14 are Edge and LT who will both be in the HOF. 8/14 of the players above played in more seasons than Gore. 4/14 have played the same amount of seasons as Gore. Gore has made 5 pro-bowls and played on some truly awful niners teams. He has 70 Rushing TDs which puts him 30th all time. Today, I think he gets in because he hit 12,000+ rushing yards and due to the NFL's track record at that number.
If Gore plays this season and has 700 rushing yards, that would put him 8th all time. Gore is 206 rushing yards away from being in the top 10.
Gore is the Don Sutton of RBs. He might eventually get in on longevity and consistency. But that shouldn't be the standard for the HOF.
I think a guy like Sean Taylor is far more deserving because he was a transcendent player even though he didn't play very long.
First, I do admit that Frank Gore was never the standard or the best in the league. He was a constant very good back on a bad team.
Second, a strict statistical analysis. Don Sutton was a tremendous compiler and I don't think the analogy to Don Sutton is fair though. Of the players listed on the all time rushing list, 8/14 have played more seasons than Gore. Going on a game by game basis, Frank Gore has played in 164 games. Of the 5 people in front of him, only Edge (148) has played in less games. Thurman Thomas (182), Franco Harris (173), Marcus Allen (222) and Marshall Faulk (176) have played in more games than Gore. The leader of these five (Faulk) has only 205 more rushing yards and played in 12 more games. Gore, last season, still finished 9th in the league in rushing. The guy is still putting up good numbers and is finishing in the top 10 in the league.
Sutton, after 1982 when he had his last season in the top 10 in wins, played 6 more seasons. Those extra 6 seasons were nothing like the previous ones before it, yet he relied on those seasons to make his way into the HOF. He needed those 60+ wins to get him into the 300 win club. I don't think this applies to Gore. Gore already has the 12,000 rushing yards and he did it in less games than 4/5 above him.
Third, I get what you're saying about Taylor but it doesn't really matter here. It isn't either Gore gets in or Taylor.
