Agree, but minor correction. McDavid did miss two games (Kuch missed one), so he's only going to play at most 80 games to MacK's 82 and Kuch's 81...
But your broader point is correct, winning it is winning it.. you need both skill and health.
This is still very much a 3 horse race. McD only needs a 5 game 2 point/night heater with his games at hand (the one's he'll actually get to play) and he'd effectively be within 3 points of Kuch with 16 games left.
But speaking for all Oiler fans, I just want to see effective 5v5 play from now until the end of the season... McD has been leading by example and that needs to continue.
