I might not put him in my top 5 all-time but he was my favorite non-Bill growing up. The fact he was a lefty like me probably had something to do with it, but I also loved his kickass, take-no-prisoners swagger. It's a shame he's not in the Hall of Fame for whatever reason.
Your mentioning Mark van Eeghen calls to mind an anecdote from Madden's first book, in which a not-too-bright defensive end named Charles Philyaw went to Madden and asked to have his first name AND his last name on the back of his jersey.
"But we don't do that," Madden replied.
"Yes, you do," said Philyaw, pointing. "See? VAN Eeghen."
