McMann scored a power-play goal in Saturday's 3-1 loss to the Oilers.
The 30-year-old tied the game at 1-1 in the second period by going top shelf on Devon Levi from below the faceoff dot, but it was the only offense the Kraken could muster. McMann produced career highs with 29 goals and 46 points last season in 78 regular-season games split between Seattle and Toronto, and he'll have a good chance to repeat those numbers in a top-six role and spot on the first power-play unit.
