Last Season

Three goals and one assist in 38 games — four points, minus-six, at 9:09 a night with 43 penalty minutes.

His 265th career game.

The Finesse Game

Sixty-four unblocked attempts, three goals, median 21 feet with 45 per cent from inside twenty. The location is fine and there is nothing behind it.

Thirty-nine points in 265 career games — fourteen goals across nine seasons. One assist in 38 games is close to the lowest return in this book.

The Physical Game

Six foot one, 215, and the job is fighting. Forty-three penalty minutes in nine minutes a night is a high rate and he is one of the more willing heavyweights left in a league that has largely stopped carrying them.

The skating is poor and it is why he cannot be given twelve minutes.

The Intangibles

Forty-six point seven per cent of the expected goals, 24th percentile, and 48.9 per cent of the shot attempts, 44th, across 343 minutes, with the goals 24-16 in his favour.

That is a small sample and a fair one for the role, which is more than most pages like this can say.

One point in his last ten, and it was a goal. He is 32, undrafted, and has made a nine-year career out of a willingness that the sport values less every season.

The numbers are colder on him than this report is — worth asking who he played with, and against whom.
