Ouch, are there no other options for TE on the wire? (I'm assuming no). I'd go with Walford there but wow that's rough.
At RB, I'd go with the guys who are going to get touches. So Brown would be locked in for me. But I'd roll Starks as well as I'm not inspired by Lacy's play and I think Starks has a better floor than Polk out of your timeshare options.
