Mika Tafua, Cole Fotheringham, Johnny Maea, Pita Tonga, Simi Moala (Utah)...
...Levani Damuni, Houston Heimuli, Tangaloa Kaufusi, and Gabe Reid (Stanford); and Tayler Katoa (USC).
Probably several others.
FWIW, we'd have Bernard and Reid starting at LB, Tafua at DE, Covey and possibly Fehoko at WR, Tonga (if healthy) on DL, Fotheringham would be the #2 TE we desperately need, and Maea and Moala would be in the two-deep on o-line, possibly starting. Tolutau would fit in there somewhere.
