Wesley, Fusi, Yeck, Stringham and Kafu have all started in the past (though some aren't now admittedly).
That's 5 scholarship OL. I think there are only a couple missionaries returning so I would expect some more guys to be brought in. I expect at least 1 JC, maybe 2.
I don't know if Koroma will serve a mission or not.
My guess at bepth would be something like:
LT Lapuaho, Hoyt?, JC
LG Johnson,
C Koroma, Alleto
RG Kearsley, Kunuch
RT Matthews, Wilcox
Depth guys: Dawe, Mulitalo, Kaluhiokalani
OL might be a little leaner next year. Nice top 7, but lean after that.
