Seabrook has built a reputation as a clutch player in the postseason.

He scored in overtime in Game 7 of the second round of the 2013 Stanley Cup Playoffs as the Chicago Blackhawks rallied from a 3-1 series deficit to eliminate the Detroit Red Wings on the way to the title. He also scored in OT in Game 4 of the Cup Final against the Boston Bruins that spring.

He had an assist in his NHL debut for Chicago against the Anaheim Ducks on Oct. 5, 2005, then had four assists in his second NHL game two days later against the San Jose Sharks, matching a franchise single-game record for points and assists by a rookie. Seabrook scored his first NHL goal Nov. 2, 2005, in overtime against the St. Louis Blues and played for Canada at the 2006 World Championship.

Seabrook played in the YoungStars Game as part of the 2007 NHL All-Star Game festivities. Among Blackhawks defensemen in 2007-08, he was first in assists (23) and tied for the lead in points (32). He led Chicago in hits (224) and blocked shots (113) in 2008-09.

Seabrook got his first playoff point with an assist on April 18, 2009, and his first NHL playoff goal April 25, 2009, each coming against the Calgary Flames. He led the Blackhawks with 153 blocked shots in 2009-10, then had four goals and seven assists in 22 playoff games to help Chicago win the Stanley Cup that year (he had seven points in four games from April 24-May 3, 2010). Seabrook also won a gold medal with Canada at the 2010 Winter Olympics.

He was one of seven NHL defensemen to have more than 100 hits (106) and blocked shots (103) in 2012-13 as Chicago again won the Stanley Cup.
