The Toronto Maple Leafs' inability to defend has hindered their progress in recent years, but they appear to be turning a corner this season and allowed just one goal over nine periods in a three-game sweep of the Edmonton Oilers.

Toronto held the NHL's leading scorer, Connor McDavid, pointless in three straight contests for just the third time in his career, according to Sportsnet. The Oilers captain couldn't offer an explanation as to how the Leafs shut him and his club down.

"For whatever reason, we couldn't figure those guys out and they had us pretty figured out," McDavid said following Wednesday's 6-1 loss.

Fellow superstar Leon Draisaitl, who picked up one assist in the three-game set, was equally mystified.
