So your solution is to trade a borderline #1C or atleast a solid #2 for...nothing? Draisaitl was ahead last year because, if you noticed, RNH was injured for the vast majority of it. And even last season, which was Draisaitl's best season, he didn't hit the point totals RNH hit previously or play the defensive game RNH played. Recency bias screws people's minds on these boards.
From an outsider's perspective, I think people value Drai over RNH simply because of contract status and bang-for-buck value. They both have very high ceilings, but sort of play different roles (RNH a two-way game, Drai can be a game breaker). RNH is signed for 6M for the long term, and Drai is on his ELC. As a Jackets fan, I would have extreme interest in acquiring both, but would prefer Draisaitl to Nugent-Hopkins.
