Defensive tackle Mike DeVito, who's signing in free agency flew under the radar, has been a big reason that Kansas City is allowing 17.2 points per game, fourth-best in the NFL.
Just peruse the roster. There are more guys from Ivy League schools (Mike Catapano from Princeton and Josh Martin from Columbia) than from Alabama (Nico Johnson). More guys out of tiny California (Pa.) University (Rishaw Johnson,Cheap MLB Gear, Eric Kush) than Oklahoma (Donald Stephenson). And twice as many players from Central Michigan (Eric Fisher, Frank Zombo) as Michigan (Junior Hemingway).
