Do people really think SJ will receive more for Hertl then a recent 1st round pick, another 1st round pick in the coming draft and a useful roster player? Because I doubt they'd do much better then that. This obviously assumes that SJ can't or won't bring Hertl back, which I'm sure is not how most Sharks fans want this to unfold.
I can’t speak for all Sharks fans, but if the team elects to trade him, or if Hertl makes clear he’s interested in moving on - then a recent top pick + 1st + roster player seems like the standard get for a player of Hertl’s caliber as a rental. I could see additional minor considerations for any retained salary and/or if Hertl resigns with the acquiring team.
However, based on the posture of the front office I don’t see anything happening until the deadline approaches.
As far as I know the only public comments that either party (Hertl/Sharks FO) have made is that they haven’t had meaningful talks about an extension, that they will get together to discuss at some future point, and that Hertl wants to be on a team that will consistently go deep in the playoffs/contend. Hertl did offer up, unprompted, that he’d consider signing for a little less to help a team be in a better position to consistently win (for whatever that’s worth).
Who knows what Hertl might look at to determine what teams are “contenders”, but realistically, I’d wager Buffalo would not meet those metrics.
