FILE - In this Sunday, Sept. 24, 2017, file photo, Buffalo Bills players take a knee during the playing of the national anthem prior to an NFL football game against the Denver Broncos in Orchard Park, N.Y. What began more than a year ago with a lone NFL quarterback protesting police brutality against minorities by kneeling silently during the national anthem before games has grown into a roar with hundreds of players sitting, kneeling, locking arms or remaining in locker rooms, their reasons for demonstrating as varied as their methods.
