Rudi was one of the first players to truly usher in my fanhood. I didn't really care about football until after Ohio State won it all in 2002 (go figure, I don't give a crap about them now), and I decided to watch the Bengals in 2003. The unique character of that season was perfect to pull me in permanently, with Kitna playing way over his head, beating the 9-0 Chiefs, and having Carson Palmer sitting on the bench waiting to elevate the team in the following seasons.
But there was also Rudi, playing in Corey Dillon's place most of the season, blowing up the stat box and earning his signature RUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUDI chants at Paul Brown Stadium. It's deeply unfortunate to lose him, especially in that way. Given the means and the age, it's difficult to look past the specter of CTE. Who knows.
