One of the big things the Oregon ducks had going for them was the return of all 5 OL starters. With their LT tearing a acl this could possibly weaken their whole unit. LT is most certainly the most important spot on the OL so we have to assume that Johnstone was their best Olineman. Not sure yet who will replace him but in most cases it involved shuffling of other along the OL when you are filling suck a valuable spot as LT. Anyone else with any more insight into the situation feel free to add. I'm betting this news doesnt have any Spartan fans crying.
