The postseason, however, was a different matter. The right winger averaged nearly 14 1/2 minutes of ice time per night in 11 games and had no goals and just one assist.

Asked what ailed Perron, Blues general manager Doug Armstrong responded: "If I had known a reason earlier, I would have shared it with him."

Armstrong added that he and Blues coach Mike Yeo would review the video from the playoffs in the coming weeks and look for answers.

"One of the things that I admired for David (in three previous postseason appearances with the Blues) was his playoff participation," Armstrong said. "He had (LA goalie) Jonathan Quick tied up in knots. We didn't get past him, but he was able to disrupt the flow of the game with his tenacity and for whatever reason, whether he couldn't find the right matchups or he couldn't find the right mojo this year, he didn't have that same effect.
