The Toronto Maple Leafs are entering a pivotal offseason, and after a disastrous 2025-26 campaign, one thing is crystal clear: their blueline needs a major overhaul. If they want to make a serious playoff push in 2026-27, upgrading their defense is non-negotiable. Here are three prime targets who could transform their back end.

1. Rasmus Andersson – The Complete Package
If Rasmus Andersson hits the open market, the Maple Leafs should be first in line. The 29-year-old right-shot defenseman brings exactly what Toronto lacks: versatility, offensive pop, and reliability in all situations. Splitting the season between the Calgary Flames and Vegas Golden Knights, Andersson posted 17 goals and 30 assists for 47 points in 81 games, with a plus-4 rating. He can quarterback a power play, kill penalties, and log heavy minutes. Signing him would instantly give Toronto a top-pairing anchor.

2. Darren Raddysh – The Power-Play Specialist
Darren Raddysh is another name the Leafs should circle. The 30-year-old Tampa Bay Lightning defenseman had a breakout season, notching 22 goals and 48 assists for 70 points in 73 games. A whopping 10 of those goals and 26 points came on the power play, making him a lethal weapon with the man advantage. Raddysh would slide into Toronto's top four and provide the offensive spark their blueline desperately needs. Expect stiff competition for his services, but his skill set is a perfect fit.

3. Colton Parayko – The Steady Veteran
If St. Louis Blues defenseman Colton Parayko is willing to waive his no-trade clause, the Maple Leafs must make a strong push. At 6-foot-6 and 32 years old, Parayko is the prototypical shutdown right-shot defenseman Toronto has been missing. He's not flashy, but he's reliable, physical, and can neutralize top lines. More than just a rental, Parayko would bring stability and experience to a young, struggling blueline. He's the kind of player who can help turn a weakness into a strength.
