Let's talk about the playoffs. He had some key goals, absolutely but what was his overall contribution?
FO stats (OZ/NV/DZ)
KK: 51/65/38
Suzuki: 148/94/86
Danault: 77/126/301
The team simply did not trust him at all for faceoffs, especially in the DZ. Danault had to take the vast majority of them to allow the others more offensive deployment. Scoring points was all he had to do.
Here is his game-by-game log:
NHL Stats
As you can see, after the first game of the 2nd round he had 1 goal and 3 assists in 12 games. He had zero PP points in 25 minutes in total in the playoffs.
This isn't really the kind of contribution we expect from a "2nd line Center" with the quality of the minutes he had. Who knows what could have happened with Dvorak instead of him on the team?
