Unfortunately, it was inevitable. Anyone who has watched Seabs play the last two seasons could see this day coming rapidly. The mobility was completely gone.
3 time Stanley Cup champion and a gold medal winner in 2010. He always played the hardest minutes; penalty kill, defensive zone draws, other team's top lines, Seabrook got all those assignments. Took hits, threw hits, blocked shots, and he was just a solid stay-at-home defenseman. He even chipped in a clutch goal every now and again. And he played the game the right way.
Seabrook was also a great teammate. He would be the one to chaperone new free agents upon their arrival; help get them acclimated to the city, show them where are players live, shop, eat, etc... He also opened his home to new draft picks, many young players have called the Seabrook residence home, from Jonathan Toews and Brandon Saad to Alex Debrincat and Kirby Dach, they all spent their first season living with the Seabrook family.
No doubt Brent will get his retirement ceremony, but I'm sure the Hawks will wait to do it the right way, in front of the fans so Seabs get his proper due.
