This is another good play out of SG 4WR set. its a good play for those short yardage or medium yardage gains.
Here is what I do to make this play money:
hot route your #1 WR to do an out route and smart route it so its at least 10 yards.
hot route the HB to run a curl or slant to the INSIDE.
your looks will be the HB, #2 WR, then the inside WR's on the corners, then the #1 WR. these are all in order form 1st to last look, so look for theose ppl.
