Schenn has 28 points (12 goals, 16 assists) in 61 games this season. He is in the sixth season of an eight-year, $52 million contract ($6.5 million average annual value) he signed with the Blues on Oct. 24, 2019, and can become an unrestricted free agent after the 2027-28 season.
The No. 5 pick by the Los Angeles Kings in the 2009 NHL Draft, Schenn has 713 points (290 goals, 423 assists) in 1,083 regular-season games for the Kings, Philadelphia Flyers and Blues, and 43 points (13 goals, 30 assists) in 82 Stanley Cup Playoff games.
Schenn, who was captain of the Blues for the past three seasons, helped them win the Stanley Cup in 2019.
"Leading up to the Deadline, with all the rumors and where we're at, you think about it quite a bit. It's a great place with a great organization and good team. I think what people don't realize about it is the human element of it," Schenn said. "As you get older, guys have families. There's all that part of it that comes with pro sports, but we know what we sign up for. It's emotional.
"St. Louis was a great spot for me; probably the best thing to happen in hockey for me up until this date. Playing with just a bunch of good, solid people; great community, city, and won the Stanley Cup there. It's been a special place for me and my family. Going to miss St. Louis, but excited for the next chapter."
The Islanders (35-23-5) are tied for second in the Metropolitan Division, three points ahead of the fourth-place Columbus Blue Jackets. New York next plays at the San Jose Sharks on Saturday (10 p.m. ET; MSGSN, NBCSCA).
"We always said we want to be hard to play against,” Islanders general manager Mathieu Darche said. “We wanted some [snarl]. Brayden fits that -- you should see the text we got from former players and players that have been with him, and the type of player he is.
“He's a playoff guy, he plays hard. If something happens, he's not afraid to defend a teammate. He's scored 20 goals multiple times in his career, so we just feel he's going to help us out down the middle. … He's a competitor; that's what you want at this time of year. When you play hockey after the Deadline and in the playoffs, it's fighting for every inch on the ice, being able to take a hit and dish out hits. We want to be physical, and Brayden does that. So, I think he fits exactly what we need right now.”
