I think I was the one that said the OL needed to show improvement, and it's true. While the OL (and Taysom Hill) dominated Texas on the ground, there were other games last season where our QB didn't have time to throw the ball the way we wanted him to. Everyone is looking for OL improvement this year even though we did roast Texas. Sounds weird, but it's not disingenuous.
And a last note on missionaries, of the 5 offensive lineman who are currently listed as starters (though some positions are still up for grabs), only two are returned missionaries.
LT, Wesley, not LDS
LG, Johnson, returned missionary, served 2 years before he started playing so he was a freshman last year and is starting his sophomore year.
C, Fusi, not LDS
RG, Kearsley, LDS but not planning on a mission. Was a true freshman last year.
RT, Lapuaho, returned missionary, served 2 years before he started playing so he will be a freshman this year. [his BYU player profile says his favorite food is horse meat. I think BYU fans are going to like this guy.]
