Is he Mormon? I hadn't caught that anywhere.
Yup. He says he is going on a mission but that could change, especially with a guy going here rather than BYU or Utah. Thing is, if he goes on a mission not only is he not playing for a couple years(which is OK long-term but hurts short-term) but he could always opt for another program afterwards like Ben Olsen did.
Are we sure we aren't confusing Siosaia Tuipulotu with Latu Heimuli? Siosaia is from Tonga. I'm not sure what the Mormon population is there, but it can't be very large. That puts the chances at him being Mormon very small. On the other hand, Latu is from Utah and lists BYU as his favorite, although he has interest in Nebraska.
No he's definitely mormon. Latest rivals update says he wont be playing football till 2011.
