This is who I think gets in:
Kurt Warner, Isaac Bruce, Orlando Pace, Kevin Greene, Junior Seau, Don Coryell.
In no particular order.
I realize it's Ram heavy. That's incidental and unfortunately it may hurt guys like Kevin Greene or Isaac Bruce which is a shame.
I looked at all those guys and this is the list I would go with. Then again, I haven't heard anyone "make the case" the way the writers make the case for some of these guys do. Some of these cases are...very compelling.
But...Kurt Warner. 2 x league MVP. 3 highest yardage totals in Super Bowl history. Super Bowl MVP. Took 2 historically bad teams to the Super Bowl, neither of which has tasted success since he left.
Isaac Bruce. 1781 yards from Chris Miller in 1995. Let's just let THAT sink in. And that would have been an NFL record until 2012 when Calvin Johnson broke it, except Jerry Rice had 1848 yds that same year. And he had a slightly better QB... Game winning catch in the Super Bowl, one of the best route runners to ever play the game and over 15 thousand yards, part of the GSOT. His single year total is still the 3rd highest... of all time. If Jerry Rice is #1, Isaac Bruce is 1a.
Orlando Pace. A prototype LT who dominated in a way few others have. The awards are too numerous to mention. He beat normally dominating defenders with power, grace and technique. He was flagged less than once per year for holding during his career, a staggering stat.
Kevin Greene. One of the best 3-4 OLBs to ever play the game. His 160 sacks is MORE than Lawrence Taylors and if it weren't for the lost year of 1996 with the Rams converting to a 4-3 DE under Jeff Fisher (yeah...) and the 1997 lockout, he could potentially have had 20+ more sacks on his resume. With every team he played with, Rams, Steelers and Panthers, he demonstrated that he was one of the greatest pass rushers of all time.
Junior Seau. One of those special players that just can't be fully accounted for because he was unconventional. His brain was just on another level. He found a way to the football that only revealed its way to others on the tape...later. During the game, he just...attacked. And attacked. And attacked. The Hall of Fame is reserved for special players who change the game and the position and Junior Seau did just that. Even during the latter stages of his 19 year career, he found ways to be special.
Don Coryell. If ever there was an offensive mind and innovator who changed the game, it was Don Coryell. His Air Coryell offense is still used in variants today. I could go on and on about Don Coryell and his offense, but that requires almost a book to be done properly. Of everyone on this list, Don Coryell deserves to be in the hall MOST. You simply cannot talk about modern NFL offenses without talking about Don Coryell. He changed the game. Greatly and for the better.
