The answer is obvious but many don't want to hear nor accept it.
Internal team salary/cap comparables vs external comparables.
Aho in Carolina does not have any $11 mil dollar teammates on their roster that score more points than he did. Aho couldn't even get $8.5 mil X 5 offer from his own team and needed a 3rd party team through the inflationary OS process to get the contract he wanted in order to make himself the highest paid Hurricane.
Marner could care less what Aho a statistically reasonable comparison to himself makes, because he is Leaf and not a Cane.
If Marner were in TB and Kucherov signs for $9.5 mil X 8 years after 128 points and Stamkos re-ups for $8.5 mil X 8 years after scoring 45 goals and 98 points this last year, as they finished 1st and 9th in OA NHL scoring, then could Marner coming off a 26 goal and 94 point season really be demanding $10.5 mil or more on a short-term deal as his internal comparables?
Its just like in Real Estate its Location Location Location.
