As a Jets fan I gotta go with Ehlers or Trouba...
Let’s start with Ehlers, his regular season point totals where slightly disappointing(60pts) but his lack of PP time and overall even strength minutes didn’t help, that said his pts/60 and especially his pts/60 5v5 where amazing. But what I’m most disappointed in is his abysmal lack of scoring in the playoffs. Going forward a better Centerman(who can score or make plays) for most the season, more minutes 5v5 and on the powerplay should really bump those numbers and play up.
Trouba, pretty much the same thing for Trouba as for Ehlers, lack of PP and ES time because of Buffs offensive talents. Also was pretty bad offensively in the playoffs. Just like Ehlers it should be fixable as his scoring analytics where great just his minutes in scoring opportunities where limited, that said he was excellent defensively for nearly all season(I still hope he rounds out at a 40-50pt D-man who can play good defence, just gotta hope he gets more minutes for that as well and it will be possible).
