Poop in his big boy pants Pryor or hot off the press sterling Shepard?

I’m in a 12 man ppr league and I need to figure out who I want to start at my 2nd receiver spot or flex. I could either go with Pryor who’s been a disappointment so far, Shepard, or I have cupp as a sleeper on my bench as well.

Thanks for any advice in advance

I might roll Shepard out there because I’m scared of Marcus Peters. My want to check if Tampa DBs are practicing, I think Heartgraves went down last week.
