The defensive line looks to be in reasonably good shape in 2015. However, both high school and JC d linemen look to be a priority in the 2016 recruiting year. Depth chart for 2015 looks like this to me (based on most recent roster):
DT : Grimble Sr (291) Peko SR (306)
Robins Sr (289) Tago Jr (304)
Houston Rfr (276) Vakameilulo Rfr (318)
Filipe Sr (293)
Add Elu Aydon (310) to this group, who I believe will red shirt .
DE : Barnett Sr (262) James Sr (264)
Failauga So (250) Hollingsworth Jr (270)
Pritchard So (258) Williams Rfr (267)
Add Simi Moala (240) to this group, who may be going on a mission and enter in 2017.
Seem to have better overall size than I remember in sometime, but with four out of eight being seniors will need help soon. This could influence a move of one or two offensive linemen to defense to even out classes.
