The Kansas City Chiefs have a new starter at right tackle: Ryan O'Callaghan. Acquired off waivers on September 6th, O'Callaghan came from the New England Patriots, formerly the home of GM Scott Pioli. There's also a new starter at nose tackle: Ron Edwards. Tank Tyler has been the No. 1 nose tackle since the beginning of the season and started the first two games. Edwards got the starting nod against the Eagles on Sunday.
