Specifically, I dont like him starting with Chris Paul. I think you would be much better of benching him in favor of Ariza. Igoudala would give you a defacto backup PG to Paul, which would be huge for you since you have no backup PG.
I assume you mean I bench "Iggy" and not "CP3"?
Prefer Avery Bradley and Manu to Iggy as backup PG. But that said, Ariza starting and Iggy as sixth man would be pretty sweet.
