Yes. Jett is still getting paid his full salary. The two way guys (Queen, Harris, Schofield) make half a million a season. Exhibit 10 guys (guys who were with us for preseason and then went to the G league, so like Matt McClung etc) get a bonus that can be up to 75k from the Exhibit 10 contract and then their G league salary on top. The standard, I believe flat, G league salary is 40.5k for the 5 month season.
Also worth noting a lot of G league guys could go overseas and make more money (the average euro league salary is like 400+k a year but some guys make legitimately more than an NBA minimum salary) but being in the US means they can be signed to 10 day contracts which could help them get full contracts and the real money. Plus there are obviously family/culture reasons to stay in the US.
Long story short, no need to feel sorry for them.
