Nylander is not better than Pastrnak
Marner is not better than Kucherov
Matthew's is not better than McDavid.
That's the basis of those numbers
The cap goes up each year. If that didn't matter, no one would have been making more than $8.7M all these years.
Nylander has a lower cap hit % than Pastrnak. In other words, Pastrnak's deal was $7.07M adjusted for last year's $79.5M cap, the first year of Nylander's deal at $6.96M/year (first year pro-rated).
Matthews deserves a full $2.5M less annually than McDavid, even factoring in the large cap increase between when McDavid signed and Matthews signed? That's nuts. Matthews' first year of his new deal will come in at around 14% cap hit, which puts him beneath deals signed by Kane, Toews, Malkin, Crosby, Karlsson and right around where Kopitar and Price signed.
None of your numbers introduced term into the equation, either.
This isn't about how you feel they should be paid. Market valuation doesn't take into account what you want them to be paid.
