starters
return a true starting QB
2 talented RBs
Trinnaman, MLP, Simon at receiver
OL has Koroma, Lapuaho, and Kanuch who will all likely be 4 year starters together. Then they'll have Hoyt, Nwigwe, Longson, Norman, Tanoai and others. Guys like Dawe will have built up size. There's always the possibility of Joe Brown if that ever gets worked out.
DL will have Laulile, Kaumatule, Tanielu, Mounga, Taliauli, potentially Takitaki, Fuiava, Leiataua, hopefully Saleapaga, etc.
LB will return all 3 starters including a star
Corner will have a lot of talent.
There could always be JC transfer help. I'd almost expect something like that for safety. I hope. It's a good spot to get JC guys. Armstrong could be a starter there next year as well and they bring back Hannemann.
All of the mission talent from when recruiting started getting better in 2014 will be in the program and going. Some of the 2015 class will be back and there always seems to be an RM who steps in and surprises.
