The Kings want more experience on the roster. How they go about that remains to be seen.
The Kings have already reached out to their own big free agents - Samuel Dalembert and Marcus Thornton.
Both players would be more experienced than options the Kings have for depth (Hassan Whiteside or Isaiah Thomas) which is what the Kings want.
Hayes is only 6-foot-6 but started at center in Houston and is noted as a defender. Barea is generously listed at 6-feet tall and was a star off the bench at times during the Mavericks title run.
But it's too early to read too much into merely contacting their agents. If the Kings re-sign Dalembert and Thornton, the Kings would still be in the market to make trades to upgrade the roster.
