Veteran defenseman Brent Seabrook is slumping conspicuously in the Chicago Blackhawks' second-round playoff series against the Detroit Red Wings and Joel Quenneville is doing something about it. The Hawks' coach is cutting Seabrook's playing time. Seabrook's playoff-low 12:03 of ice time in the Hawks' 2-0 loss to the Red Wings Thursday is an alarming number for a player of his caliber - an eight-year veteran in the middle of a five-year, $29 million contract. He averaged 22:00 of ice time in the regular season, second highest on the team behind iron man Duncan Keith. The 12:03 against the Red Wings in Game 4 is the lowest time-on-ice of Seabrook's 658-game NHL career. His previous low was 13:27. He's never played less than 16:00 in a game over the past six seasons. Seabrook has contributed very little offensively and is a minus-4 against the Wings.
