"They're a hard-nosed team; they've got a lot of depth," Clifford said. "They're always tough to play against and I just think I fit in really well. I'm looking forward to getting down there, helping to contribute and the idea is to win another Stanley Cup."
Clifford won the Stanley Cup twice with the Los Angeles Kings (2012, 2014).
The 29-year-old forward scored 17 points (seven goals, 10 assists) in 69 games with the Toronto Maple Leafs and Kings last season, including three points (one goal, two assists) in 16 games after he was traded to the Maple Leafs on Feb. 5. He did not have a point in five games in the Stanley Cup Qualifiers.
Selected by Los Angeles in the second round (No. 35) of the 2009 NHL Draft, Clifford has 132 points (61 goals, 71 assists) in 676 regular-season games and 15 points (four goals, 11 assists) in 60 Stanley Cup Playoff games.
"I just wanted to set myself up for the best chance for success," Clifford said. "I thought St. Louis, they've gone far along. Obviously they won a Cup (in 2019) and [I'm] confident that I can contribute down there and hopefully we can bring another Cup home to St. Louis."
