Gauthier is unproven at the NHL level, Cates is a natural LW. If michkov comes over as a center theres no need to have Cates play center, and his defensive game is already NHL level so he makes the most sense. Gauthier is more of a scorer, Farabee isnt known for his defense either so it didnt make sense for him to play top line. We already know Cates can play top line minutes against top lines,, and 3 years from now he's probably gotten better at it.
Cutter will possibly be a 2 year NHL player by the time Michkov comes over and if Cutter can't even cut the 1LW over Cates by then, then Cutter, just, well, doesn't cut it?
