ENGLEWOOD, Colo. -- If you want to play on Bill Kollar's defensive line, you can't do just one thing. That's why free-agent pickup Vance Walker might be an ideal fit for the rotation up front.
From Georgia Tech to Atlanta to Oakland to Kansas City, Walker has been a chameleon, remaking himself to fit the scheme and the role his coaches wanted him to play. That has allowed him to put six NFL seasons under his belt and ensured that he sat on the market just six days after the Chiefs released him in March.
