Peterson to be lead back in Week 9?

NFL Network's Tom Pelissero reports that Adrian Peterson is expected to be the Titans' lead back vs. the Rams tonight. Pelissero throws out a projection of "upwards of 15 touches" for Peterson. We're curious to see exactly what this Henry-less backfield looks like, with Jeremy McNichols and D'Onta Foreman also in the mix. We'd still consider Peterson just a RB3 or flex play for Week 9.
