Lineup advice for rebuild team

So after raging and selling my team then selling most of my MT I decided to keep the last 500k and build a “fun” idk. I pulled one pack of the KG packs and got Pierce so I have this team and 500k after rebuilding it basically.

I have gone 2-0 with this team so far and my bench has been killing it so far. But starting lineup has really struggled. I feel like I need to replace Kawhi. Anyone have have some suggestions on who could take his spot?
