FILE - In this Oct. 2, 2016, file photo, Buffalo Bills head coach Rex Ryan stands on the field before an NFL football game against the New England Patriots, in Foxborough, Mass. It's a free country, so it makes no difference to Rex Ryan whether Colin Kaepernick continues to kneel in protest during the national anthem when Buffalo hosts the 49ers on Sunday. The Bills coach is more concerned what the San Francisco quarterback can do with his arm and legs once the game begins now that Kaepernick has reclaimed the starting job. (AP Photo/Steven Senne, File)
