Quarterbacks Tom Brady, left, and Philip Rivers meet in a divisional playoff game on Sunday.

When the Chargers play the Patriots in an NFL playoff game Sunday, it’ll have some serious Tucson blood: Chargers tight end coach Rip Scherer was Dick Tomey’s offensive coordinator in 1989 and 1990, and linebackers coach Richard Smith was part of Tomey’s original 1987 UA staff. Former Mountain View High School quarterback James MacPherson, who played at Wake Forest, is one of the Chargers’ leading scouts.
