One food for thought item when it comes to face-offs - Rantanen was much better with consistent work.
In the games where he took 7+ face-offs (24GP), he operated at 51.6% on 250 draws.
In the games where he took between 1-6 face-offs (34GP), he was much worse: 33.6% on 104 draws.
I’ve posted it before, but I traced back 15 games last year where Rantanen was a full-time center due to injuries to one of Kadri or MacKinnon. In those games, the Avalanche went 12-1-2, Rantanen scored 24 points, and won 51.1% of his draws. (Note: these were games mostly in November and December, with a handful in Late January-Early February. Rantanen did NOT play center at the end of the season when Kadri went down; but he took many more face-offs for the MacKinnon line due to Landeskog also being injured).
