Although the Broncos fortified their two defensive end positions by adding Vance Walker and Antonio Smith to rotate with Malik Jackson and Derek Wolfe, they stood pat at nose tackle, looking for Sylvester Williams and Marvin Austin to make the transition to being on the nose in Wade Phillips' 3-4 alignment.
Williams and Austin have the size and the agility to work at the position, but lack the experience. But Kilgo has plenty of college work at nose tackle, and at 319 pounds, fits the size template for the position in Phillips' defense, and has the "immovable object" quality that one would expect from a tackle 20 pounds heavier.
