There are names other than Tuiloma inside.
Langi and Tautu will be fine if not in better position than LB
Laulile could play inside, he played 12 games. Tausinga played 11 games. Mounga played 7.
Pau'u played 8 games. Heder played 13. Sandlin played 7.
And the OL should be more than fine with starters, and the depth could be decent.
