According to famous reporter Shams and ESPN Warriors reporter Slater, Kumingga rejected the Warriors' 2-year offer of $45 million.

Shams explained that the reason was that the Warriors insisted on adding the team option to the contract and did not want Kumingga to retain the trade veto.

The Suns gave Kumingjia the best offer in the sign-on negotiation, which was close to $90 million in four years, and the last year was the player option. This is nearly $70 million more than the warriors' offer. (The Warriors' offer is 45 million for two years, but the second year is not guaranteed for the team's option)

In addition, the reason why Kumingga wanted to sign a long-term contract with the Suns or the Kings was also that he wanted a new start + more important role guarantee + starting position + respect + some degree of career control (the Suns provided the option for the player for the last year).
