Matthews will end up getting a mid-level deal - 6 years at 6.5M, or thereabouts - unless he obliterates the league. Even prodigious talent like McDavid won't even approach max deals until UFA years approach.
And ELC is three years, unless I'm mistaken.
Well, the context of my comment was comparing Matthews to Tavares:
Tavares - 2 years until UFA
Matthews - 3 years until ELC ends (or one extra year)
So one extra year. And if Matthews is playing at Tavares's current level by the end of that contract, he's going to get more than $6.5 mil, or he'll either sign an offer sheet or take a 4 year deal that takes him to free agency.
And if we're talking about McDavid, Crosby signed an $8.7 mil deal out of his ELC, and that was under a smaller salary cap. At the time, he was one of the top-5 highest paid players in the league. If McDavid is the next one, he's going to get 8 figures out of his ELC. Because 29 other teams will give him that offer sheet, regardless of cap consequences.
