An NFL Films production, "NFL Matchup" is definitely a show for football junkies. Unlike traditional football preview programs, this one gives fans an in-depth look at some of Sunday's games by breaking down the strategy and tactics -- the Xs and Os -- through the exclusive use of team-supplied footage. That type of film study is a forte of former NFL player and executive Louis Riddick and NFL Films producer Greg Cosell, whose work is featured here alongside host Sal Paolantonio.
