How much will the Rams use Corum during the fantasy playoffs?

I have Kyren and Corum, but I only started Kyren today. Is it a Monty/Gibbs situation or will it only be like this when the Rams are miles ahead?

I'm wondering if from next week I should start both of them or not. My other RB is Chase Brown. My other flex options are Henderson, Jaylen Warren and Rome.
