Logan Couture does not feel like his San Jose Sharks are playing up to their potential, and he’s not sure why.

The Sharks lost 4-2 to the St. Louis Blues in Game 2 of the Western Conference finals on Monday night to even the series 1-1. Couture scored a short-handed goal in the second to put San Jose on the board and later tied things up with his 100th career playoff point. The tie was broken later in the second, and then the Blues put the game away in the third period.

After the game, Couture told reporters that he felt like the Sharks are not playing their best. He called it “discouraging” and “frustrating.”
