That's also a very valid and fair point I may have seemingly overlooked (but I did consider). My intention was not to overglorify a straw man (Hall-Larsson is a notorious one on here), just to provide some notion of recency (Kane was the last profile UFA extended). Still, I do genuinely think 8-8.25m AAV, while certainly plausible, would (as of OEL's current stock) have to include an interplay of him providing some degree of a home-town discount. Now, the reasonable expectation may be that players do provide this, in general, if they resign with their teams before hitting the open market- which is also fair.
With a ~8m AAV contract though, I do geniuinely think he's providing a significant hometown discount- relative to his UFA worth, to the tune of ~1.5-2 million AAV per year, over a significant amount of term.
