My column for tomorrow's paper is about the changes Kirk Muller has made to the power play, and how they're starting to show results, but the comparison between what he's doing here and what he did in Montreal last season bears some further examination.

Montreal's efficiency jumped four percentage points in the final 35 regular-season and playoff games, and P.K. Subban scored seven of his 11 power-play goals over that span. Over the past four games, Carolina is converting at a 24.0 percent clip, up from 12.2 percent under Paul Maurice.

Muller has given new roles to Justin Faulk and Tim Brent on the first unit, and he's starting to see results.
