you can do that but shift to 4wr and get unbump on both slots too...
delta sit FTW
strong I has a green delta sit route that if you smartroute he wont motion and gets inside position on unbump every time i used to shift it to my singleback sets on 08 - money on the quick high pass
also i think it was slot strong has some nice ass plays, the slant curl to tall TE all day
and any set w/ 2wr on 1 side, motion rb w/ a flat route out to same side route is going & same side w/ 2 wr's - once he passes tackle snap and throw up and in its all day
