Devito is a 5-tech, but he is about the same size as Walker (though maybe heavier than his listed weight). Bailey is a 3-tech. Catapano can be a 5-tech if he has gained sufficient weight. Chiefs had Jay Howard playing nose against San Diego. IMO, Vance Walker would be a 3-tech (which is what he played with OAK).
Who is the "big 5-tech?"
