Yikes. Ehlers will have way more value over the length of his contract than Wheeler will.
Not sure how you define value, but Wheeler's has been sky-high.
He is team captain, league MVP candidate, mentor to Scheifele and stabilizing influence on a very young team.
Over the past 4 seasons, he is second only to Patrick Kane in points scored by a RW.
Last season was his most prolific yet, so he has not begun to regress.
Elite players in superb condition should not be expected to regress rapidly in their early thirties, so the next 4 years may not show as much of a decline as some are predicting.
Ehlers is a very good young winger, but has not scaled any of those heights yet. If he does indeed have "way more value" than Wheeler over the coming years, he will be considered one of the best wingers in the game and we will be that much closer to mapping out parade routes.
I would not think the Jets would consider letting either of them go.
