Hi,
I have a SG capped at around 43k of salary, which is consistent with the data Leyendinha had provided.
My guess about potential caps its not about the salary but about a combination of primary skill level for every position.
My SG is lvl1 in rebounding, and thats is the reason, or my guess, why he is in the bottom of the interval. But most important he get capped, when the summ of his 3 primary skills for SG reach 40. I assume that primary skills for SG are JS, JR and OD.
Maybe the SF get capped at low salaries because the formula takes into account more primary skills than for a SG or a C.
Also in the case of PG, many of them or at least many that i have seen(before last changes), haven't a really high level of passing, making it possible to reach their cap with a higher salary than SF. Assuming that passing is a primary skill for PG.
Best regards,
