Kansas City Chiefs defensive coordinator Romeo Crennel inherits a promising young group of defensive players that includes four former first round picks in his front seven.
Of course Crennel, like former coordinator Clancy Pendergast, prefers using a 3-4 defensive front over the more common 4-3 alignment. That said, the one position on the defensive side of the ball in dire need of an upgrade is the nose tackle position.
A nose tackle that demands constant double teams and stuffs the inside running game is critical in making the 3-4 defense work. Without it, well... the defense resembles the one the Chiefs put on the field in 2009.
Last season, with veteran Ron Edwards at nose tackle, the Chiefs defense ranked 31st in the league against the run (156.5 ypg) and 30th in total yards allowed (388.2 ypg).
As any coach will tell you it all starts in the trenches, and when running the 3-4, it all starts up the middle. If the Chiefs expect to improve one of the league's worst defenses from 2009, simply hiring Crennel to lead it won't do the trick.
Crennel will need GM Scott Pioli's help in acquiring a nose tackle who can plug the middle better than Edwards, and there are a few players in this year's draft that could fill that need.
