‘Ike Boettger, offensive lineman: The second-year lineman was on the practice squad for the first half of the year, was signed off waivers by Kansas City midseason, and fortunately was released so the Bills could get him back. On the 53-man roster for the last half of the season, Boettger appeared in four games and will provide solid competition for the veteran free agent signees at the guard and center positions.’
