They were not companions but he lived in the same house as Langi towards the end of his mission. He said the guy is the real deal. Completely raw but has extradinary strength and can move. This is from his observations on P-day playing basketball and he was also with Langi and his companion when they were invited to work-out at a member's home one P-day. Apparently Langi had never lifted weights before but bench pressed 3 plates (315 pounds) several times with ease. My cousin said it was like the scene from "Unbreakable" when they just kept adding weight to see how much he could do.
I had my doubts about him at first but after hearing my cousin speak about him, it got me very excited for his return to BYU. I think he will suprise alot of people once he gets into the weight room and starts to develop as a football player.
