Center Nazem Kadri, who was traded by the Maple Leafs to the Colorado Avalanche on July 1, said Marner is worthy of a lucrative long-term contract.
"An exceptional player," said Kadri, who along with Tavares attended the second annual Marner All-Star Invitational benefitting his Marner Assist Fund. "He's one of the best, maybe quite possibly in the League. Obviously, [Marner] deserves to get paid.
"He's worked extremely hard to get to this point. The city of Toronto loves him, and, in my opinion, I think needs him. Whatever happens, happens. But you certainly can't take away from what he's done in his first three years."
Tavares excelled in his first season with the Maple Leafs after signing a seven-year, $77 million contract as an unrestricted free agent on July 1, 2018. He centered a line with Marner on right wing and finished with 88 points (47 goals, 41 assists) in 82 games.
"I think his impact goes so far, not just on the ice, but in our locker room," Tavares said. "Just the type of person he is … obviously, the type of player, plays in all situations, and just so smart, so cerebral, elite skillset, and obviously still got so much more room to grow. We're excited obviously about his potential and what he has ahead of him."
