He used it quite a few times. It worked for a FF and sack by Woodson on one of the plays. Don't know anymore about the rest, I was too busy waving my arms around in a spastic manner out of enjoyment.
Overall, though, this formation should be great, as long as we won't get run on too much. It's great for 3rd and 10 or something. Especially if you put a lot of pass rush specialists among the LBs. Saw Jolly playing the NT in the 1-5-5 a lot, btw. Was that just because of defensive rotations, or do you recon that he will be the NT in the 1-5-5? He has been very impressive.
Maybe Foster should get us up to date on his legal issues (if he wants) now he's in the spotlight again.
