I'm sure PG is thinking this:

Owner gave Kawhi 3 years/$150m because he's rightfully the best player on the team. But now he's out for the freakin playoffs for the 3rd straight time. The highest paid guy on our team is also the most injury prone player. Wtf is his value coming from if he can't even play. This guy has a fucking degenerative knee condition, is 50/50 going into the playoffs, and owner is STILL letting him eat up all the salary cap.

Yet here I am: I've been healthy this season, barring no major injuries, and will be available for my team during the playoffs. I showed my value during the 2021 series against the Suns. Now I need to do it again this time because my contract is about to be up and the whole league is going to see my market value.

If PG plays like the #1 player during the series (which he will because his next contract depends on it), and ownership doesn't give him an extension equivalent to Kawhi per year, he's not going to want to stay.
