INDIANAPOLIS—While sorting through his stacks of unwatched videotapes Friday, Colts quarterback Peyton Manning reportedly stumbled across a strange sort of game film in which two detectives, who are apparently not involved in the playing or discussion of football, attempt to solve a murder. "I have no idea why someone would make a tape of this, since it isn't about football in any way whatsoever," said Manning, adding that there wasn't a single defensive formation to analyze in the 120-minute-long tape. "I'm told that people do this with films, and that you can even see this sort of thing on TV sometimes, but I really don't understand how two guys trying to catch the person who killed the heiress is supposed to help someone read tendencies in the Titans' secondary." Manning admitted he had not been this confused by a game film since his wife, Ashley, made him break down tapes of a football player and a woman in a cheerleader outfit engaging in an extended and vigorous, though evidently pointless, tackling drill.
