I don't know if it is 100% correct, but I just checked Kornet's contract status on Spotrac and it appears he only has a $100K guarantee. It is then $300K on 8/15. $1.07M on opening night. Fully guaranteed ($2.13M) on 1/10. And 2nd year is unguaranteed until 1/10/24
I realize Brad recently spoke highly of Kornet, and maybe he really does believe in him, but I don't think you complicate his contract details this much unless you are at least leaving open the possibility of replacing him. $100K is nothing and possibly just a 'thank-you' for being a team player.
If the team prefers Kabengele or another vet min Center and even wants to leave Kornet's roster spot open, then this allows them to do so. Maybe Kornet signs with Maine again on an Exhibit 10 contract like he did last year and we bring him up after the trade deadline if desired.
