What happened: The Toronto Maple Leafs have added defenseman Darren Raddysh, and NHL EDGE tracking data is being cited as evidence he can spark the club's blue line. The analysis frames his puck-moving and transition profile as the main reason the fit could pay off.

Why it matters: Toronto leans on mobile, right-shot defensemen to drive its breakout, and Raddysh slots into that need. This is the same sign-and-trade that brought Raddysh to Toronto, and shoring up the back end matters as the franchise looks to take a step forward next season.

What to watch: Watch how Raddysh settles into Toronto's defensive pairings and power-play rotation once training camp opens.
