Ausar is no different than any other NBA player, his value depends on what he makes.
They should offer 4/$80 million this summer. I said it a few weeks ago, Dyson Daniels is the comp for Ausar. Daniels signed a 4/$100 million extension after his third year, but he was a much better player than Ausar after 3 years.
Daniels was 2nd in DPOY voting that year while making 1st team all defense, similar to Thompson. But his stocks were 3.7 compared to Thompson at 2.9. But where he absolutely killed Thompson was on offense. 14 PPG compared to 9.9. 4.4 assists compared to 3.1. 6.8 rebounds compared to 5.7. He also took 3 3PTA'S per game and made 34% of them, compared to 0.3 attempts per game for Thompson while only making 25%.
You can't pay him more than Daniels. If you want to bump it to 4/$88 to account for the cap going up, thats fine. But if he wants anything more he needs to go show me he can do something on offense next year and we'll talk next summer when he's a restricted free agent.
