21-25.
Could be worse if the rookies don't develop, take a step back or are injured.
Could be better if everyone marginally improves and/or one or two players take a big leap into stardom (think above 17+ PER). Key to watch is Fox (needs to show he's a starter...jump from 11ish PER to above 15 or cut bait), Giles (health, upside, efficiency) and Bagley (can he be efficient and help the team win games?). We'll need continued incremental development from Buddy, Bogi, Willie (consistency mainly) to support.
If Joerger makes it to this time next year I will be shocked.
