The Toronto Maple Leafs signed and traded star right winger Mitch Marner to the Vegas Golden Knights Monday, ending the 100-point player's stint with the team and leaving a massive hole at a key position on the offensive side of the puck.

With NHL free agency opening in just hours, the Edmonton Oilers still have pending UFAs they’d like to sign, including Corey Perry. Meanwhile, the Calgary Flames have realized that trading Rasmus Andersson might be the best course of action.
