If one of them doesn't seperate themselves from the pack, the above scenario isn't a huge deal. When two QBs are brought in during the same class, I don't believe the expecation is that both will stick it out if they don't change positions, unless they are happy being the backup.
I don't see Studsrud going anywhere. He will be given the same opportunity he was always going to get to earn the job. Now he will potentially have some game time under his belt.
