Patterson starts at center, Correll moves to tackle, Lugg mans the other tackle position. Filling in the guard positions shouldn't be much of a problem, given the higher level of talent that has come in, along with some of them having played meaningful minutes. I suspect Gibbons will man one of the guard spots.
Another possibility is that Blake Fisher is ready to start at RT from day one, we can move Correll to the other guard position.
It's a far different situation than 2007. There's plenty of talent ready to be played on the line, instead of having literally only 3 true juniors and seniors available.
