WR Delimma

League is Standard and I am 10-0. Hunt and Kamara RBs with Cook as TE and Dak at QB (which is my biggest concern after ATK dismantled them last week). . My problem is choosing three WRs out of Crabtree, Shepard, Diggs, Bryant , and Jeffery. I am favoring Crabtree, Shepard, and Bryant (this would allow me to stack with Dak.)
