I assume you got this from Capfriendly. Matthews' cap hit percentage is not and never has been 14.63%.
Matthews' signing percentage is 14.0%. His actual cap hit percentage in the first year of his deal is 14.27%.
Eichel's signing percentage is more difficult because it wasn't under an announced cap, but it is likely somewhere around 13.0%. It aligns too perfectly with a reasonable cap projection (based on increases in the previous 3 years) for that to not be what they were going for.
Matthews blows Eichel out of the water in pretty much every way though.
ELCs:
Matthews: ES 15:13 (A qoc), 2.60p/60, 2.29p1/60, +0.8cfrel, +2.2xgfrel - PP 2:22, 6.31p/60, 4.90p1/60
Eichel: ES 15:19 (B+ qoc), 1.88p/60, 1.44p1/60, -0.1cfrel, +0.1xgfrel - PP 3:10, 5.69p/60, 3.79p1/60
This actually flatters Eichel for the purposes of contract valuation because this counts his 3rd year (his best), which is after he signed. It also counts after Matthews signed, when his production rate decreased.
Crosby is really tricky as a comparable because he took a very specific and special number to him that didn't really match his market value at all. Malkin is a decent historical comparable though. It was discussed earlier in this thread or a previous thread (cant keep track at this point
).
He is... but being "walked to UFA" has historically always meant that you buy no UFA years. Technically 8 years "walks him to UFA" if it applies here. Matthews' contract buys 4 RFA years and 1 UFA year.
I know you probably didn't mean anything by it, but it's really weird to see something mean one thing for my whole life, and now suddenly people are applying it to mean something different for Matthews out of nowhere. Very confusing.
