I'm fine with Davis getting in. Players can be measured in two ways. Peak value, and career value. When both are at a premium you have a first ballot HOF'er, i.e. Jerry Rice.. But when you have either one, career or peak value being through the roof that player deserves consideration for inclusion. Sandy Koufax, Gale Sayers effect one end, George Blanda, Bob Griese on the other.
A perfect example of peak value is Lynn Swann. His career stats are a joke as far as HOF status goes. But if you had an all time draft of every wr to ever play the game for their peak value not many would go before Swann. Same with Terrell Davis. For that 4 year window he was about as good as there's ever been. If you watched him at his best you'd be hard pressed to come up with more than 10 all time rb's that were better.
A similarly talented back who will likely never get a sniff of Canton is Billy Simms. The main difference between Simms and Davis is team success. But I don't begrudge Davis over Simm's omission. I think he actually emboldens his argument, and hopefully Billy will get consideration from the Veterans committee.
