I'll always say Corey Dillon should get into the HOF, especially if one of the most undeserving in Bettis got in. Dillon played on HORRIBLE Bengals teams and still produced. However, there is one player that should absolutely be in and is not, and there is not one solid reason anyone could ever give that would make sense.
Tell me how Richard Seymour is not in? Three first-team all-pro selections, two second-team all pro-selections, and the anchor of three Super Bowl winning teams on the defensive side. Hell, he was named to the NFL 2000's all decade team. It's an absolute joke that he's not in. I think he will get in eventually, just like Ty Law did.
And, no, I don't think anyone other than maybe Rodney Harrison should be inducted from those Patriots defenses of the early and mid-2000's.
