Kooch was good, but HOF?
There are already 10 offensive linemen in the HOF from the 1970s--Gene Upshaw, Art Shell, Jim Langer, Mike Webster, Larry Little, Dan Dierdorf, Ron Yary, Rayfield Wright, John Hannah, and Joe DeLamielleure. They were named to the All-Pro team at least six-times, each. Hannah was proclaimed "the greatest offensive lineman in history" by Sports Illustrated. Bob Kuechenberg was named All-Pro twice, that's why he's not in, and isn't likely to get in anytime soon. Rayfield Wright, who played tackle, couldn't make it until the seniors committee inducted him, and he was a member of the All-Decade team.
If you're wondering why Art Monk didn't make it, but Irvin did, look no further then his stats. Irvin had 7 thousand-yard seasons in 12 years. Monk had 5 thousand-yard seasons in 16. Monk only went to 3 Pro Bowls. Monk is 31st in touchdowns by receivers. That is not HOF worthy. Nat Moore has more touchdowns then Monk. Monk's career has substantial overlap with the careers of Cris Carter, Andre Reed, Michael Irvin, James Lofton, Jerry Rice, Tim Brown, Irving Fryar, how many of these players are going to make it? Fryar is not discussed for the Hall of Fame and he has more Pro Bowls, receiving yards, and touchdowns then Monk. You've got to draw the line.
There are many players not in the Hall that have bigger beefs then Kuechenberg, or Monk. Cliff Branch, Robert Brazile and Randy Gradishar to name only three. Brazile and Gradishar were simply two of the most dominant players at the linebacker position in their era. Brazile was a member of the NFL's All-Seventies team, and he can't sniff the Hall of Fame, but Harry Carson, drafted a year after him, whose career paralled Brazile's almost exactly did make it. Then again, Carson played for a two-time Super Bowl winner, and Brazile did not. The seniors committee inducted Charlie Sanders, but I've never even seen Riley Odoms nominated, and he had better numbers and played on a better team during the same era.
