Stefon Diggs Worries

Hey Everyone I need some help/advice, I’m in a Half Point ppr league with 3 WR’s 2 RB’s setup with no flex spot that vetos any type of trades and I don’t want to panic after 2 weeks but I am wondering if I should sit Diggs after his 7 target 1 reception performance last week or until the vikings show that they will have some type of passing attack involving Diggs more. Right now I have at WR- S. Diggs, T. Lockett,D.J Moore, C. Kirk and, D. Samuel with Lockett and Moore in the line up with Diggs but am at a loss on what to do.
