Actually, 4: Dulan, Manumaleuna, Fuga, Tialavea, all seniors
Ziggy was listed pre-season in the two-deep at two positions.
It's stupid to claim the coaches didn't recognize his talent, or that they didn't use him. He was in the two-deep at two different positions, specifically so they could get him on the field more. None of the DL could play OLB, and none of the OLB could play DL. Only Ziggy. It was the smartest way to get the best talent and experience on the field, and Ziggy really made the most of it.
