The nickle looked like this: Kyle Williams at NT, Arthur Moats & Chris Kelsay (both officially LBs) on the ends, Poz, Torbor, & Coleman at LB, with McKelvin, Florence, Corner, Whitner, and Byrd in the backfield. In dime, Wilson or Scott would come in for Coleman. So only 1 true D lineman on the field. DBs and LBs would be standing at the LOS and some would blitz, some would drop.
It was quite effective in creating confusion.
