I don't think it's very close, EP at .93 P/GP, with a shooting % of 19.3 finishing the season with 71GP
Brady will finish with .64 P/GP, with the same # of games played.
Dahlin would be the closest to EP playing all 82 games with 42Points for a rookie Dman, that's pretty impressive but I don't see it being enough to beat out Elias IMO.
