I like Key a lot based off what I’ve seen and the progress he’s shown, but a bunch of the same things were said about Brady Skjei after his first year. Size, good speed, offensive prowess (Skjei had a 40 pt rookie season), could carry the puck pretty well and even take the puck end to end for offense. He flat-lined/regressed the following year when he was asked to do more on the top pairing (if memory serves me right). The Rangers inexplicably gave him a big deal after that, which was highly risky the second it was signed because they didn’t have a good idea which direction his career was going after that season.
Miller’s positioning improved throughout the year, particularly since January or so, but it is still a bit suspect especially in the DZ. Not unlike Skjei’s issues. There’s still at least some level of doubt in my head about which way Miller will go. Where KAM differentiates from Skjei is he had been asked to do more as the season progressed and seemingly elevated his play, so there’s some good hope this isn’t Brady Skjei part two, but I think we have to pump the brakes a touch…
