My guess:
LT - Derek Farniok, Kenyon Frison
LG - Jamal Danley, Jonathon Alvarez
C - Ty Darlington, Alex Dalton
RG - Nila Kasitati, Dru Samia
RT - Josiah St John, Orlando Brown / Joseph Paul
So, the only newcomer to the offensive line would be Jamal Danley. He was ranked as the #1 JuCo guard.
This list also assumes none of the freshmen are ready, but Dru is thrown in at guard because that's where we're the thinnest. Either that, or one of our more senior tackles moves to guard, but I'm not confident in that - most of our tackles are too tall/lean for the guard position.
Ty Darlington - 25 games with 14 starts
Derek Farniok - 17 games + 10 more on special teams
Josian St John - 8 games - JuCo #6 player
Jamal Danley - JuCo #1 guard
Nila Kasitati - 29 games with 13 starts
I don't think our starting squad should have much of a drop-off from 2014. It's the second squad that's going to be a bit scary. Hopefully Alex Dalton comes along fast, and also that Ty Darlington stays in the game often with the newcomers to provide direction for them. Talent should be high, but cohesiveness will be OJT.
