Flip Sanders for Diggs?

I have Sanders in standard and full PPR. Sanders has been on fire but has some concern about regression. Schedule is tasty. I think I could trade for Diggs who has been down points the past few weeks but is getting a ton of Targets. I really love talent of Diggs and feel like I need to buy before he blows! Also have Cousins. Wouldnt mind the stack. Thoughts?

Any thoughts on this?
