So looking at it in those two ways, we agree the takeaway is that he'll be a point-per-game 1C with elite two-way numbers (xGF% and SCF%) if you put him with 1st line wingers? But that he can't maintain those elite numbers when playing with garbage linemates but still puts up ~60 points while being our #1 PK an face-off C? Sounds reasonable.
Just funny to see you try to summarize his entire defensive value in one number from EH while choosing to ignore the elite two-way xGF% and SCF% and GF% numbers he put up over a three-year sample. We can agree he isn't that elite pure defensive guy like Backlund. Instead, he's a quality two-way guy who can be the defensively responsible one with offensive-minded 1st line wingers. His defensive numbers won't wow you in isolation, but his overall impact at both ends (like finishing top-20 among all C's in xGF%, SCF%, and GF% from 2020-2023), in addition to his big role on the PK and PP, makes him a very valuable top-6 RHC.
I think we agree his value is very similar to Horvat and that he can be a high-end 2C or low-end 1C. So this offer is fair value. You might not wanna pay it, but a 1st+B prospect+cap dump isn't some crazy price for the top rental on the trade market. We'll easily find a similar offer from a Colorado or Vegas or actual contender that is willing to sacrifice futures to win this year.
