FILE - In this Oct. 14, 2007, file photo, Kansas City Chiefs tight end Tony Gonzalez celebrates a touchdown catch during an NFL football game against the Cincinnati Bengals in Kansas City, Mo. Gonzalez is wrapping up a 17-year career in which he was one of the best tight ends in NFL history. He never played in a Super Bowl but he leaves the game at 37 with no regrets, particularly in delaying retirement one year to play a final season that went all wrong for the Atlanta Falcons.
