Seeing as Tom Brady is the only person you seem to care about or think did anything I will quote his letter to the hall of fame.
As someone who faced him every day in practice for eight seasons, I can tell you, Richard Seymour was a menace. At 6-6 and nearly 320 pounds, he was tall, yet an immovable object, with the ability to wreak havoc in the trenches. He was smart, he understood the game and accepted his responsibilities. He had an unusual combination of size, strength, speed and athleticism. Coach Belichick stresses the importance of playing complementary football, and no one had a greater impact on what we could do defensively than Richard.
I appreciate the time and effort this committee puts into the decision process. I wouldn't write if I didn't fully endorse Richard Seymour as a deserving candidate for the Pro Football Hall of Fame. It's hard to imagine that the New England Patriots would have won our first three Super Bowls without him. He was a cornerstone of that Patriots dynasty and deserves to be recognized for his contributions to football history.
Sincerely,
Tom Brady
So just because he didn’t post a ton of stats you can point and compare to, people who know and understand football agree, and I will say it again, Big Sey was a beast and a joy to watch taking over games even when he posted zero on the stat sheet. That you think any of those other names were more important then him speaks more about you then Richard Seymour.
