Do I dare bench AJ Green for Shepard?

So I somehow managed to get Sterling Shepard off of waivers this past week (no clue why he was dropped). My current WR’s are AJ Green, Michael Thomas, Stefon Diggs, Corey Davis and Shepard.

PPR league. Do I dare go against the start your studs advice and bench AJ Green (playing Denver) or Michael Thomas (playing Washington, possibly seeing Norman) for Shepard (playing KC but off of a bye)? And if so, which one?

I would potentially flex one but I have Alvin Kamara and Kareem Hunt in my flexes right now and don’t think any of them is a better play than those two…
