EVEN-STRENGTH RATING
Rating (risk/reward rating) represents how many more successful plays each player makes than successful plays per-minute played. Rating are impacted by how involved a player is in the play. The more events they are involved in per-minute the higher their rating can become.
David Desharnais had the team's top rating in game 7. Brandon Prust, and Max Pacioretty had the top ratings among wingers, while Josh Gorges earned the top rating among defensmen in game 7.
EVEN-STRENGTH RATIOS
Ratio represents the number of successful events each player produced for every 1 failed event.
Nathan Beaulieu actually had the Canadiens top ratio in game 7. Desharnais had the top ratio among centres, while Prust earned the top ratio among wingers. Weaver had the lowest ratio among defensmen. That said, it's important to remember that these are even-strength numbers; Weaver actually produced the top short-handed ratio of any Habs player in game 7.
