He's ahead of Mag. Bosko, Mag & Catchings compete for minutes. Baker/Knell to share SG, Hall/Demin @ PG, RS/Demin @ SF.
This guess doesn't clear up who starts when Hall returns except that 1-4 positions are somewhat fungible.
Based on effectiveness so far, Catchings should come off the bench when Hall starts. Not predicting that is how it will play out.
