Ideally, a college football team would like to know its starting quarterback before fall camp opens or closes.
Unfortunately, it doesn't always happen that way.
In rare cases, a quarterback battle can linger until the start of the regular season. AJ McCarron, for example, didn't win the starting job out of fall camp at Alabama in 2011, instead vying with Phillip Sims in the early part of the schedule. Sometimes, a sample against live defenses is needed for a coach to make the right decision.
But it's not always as cut-and-dried as it was with McCarron three years ago. Sometimes, even though the coach names a starter after fall camp, the battle is not exactly over. We know who will start Week 1, but that doesn't mean the questions will subside. An example of this would be Trevor Knight and Blake Bell at Oklahoma in 2013.
The Knight-Bell situation is more common than the McCarron-Sims situation. Because there are obvious benefits to "naming" a starter by Week 1, the latter is difficult to project. But based on how close each situation appears and the timing of the quarterback's remaining eligibility, it is not as tough to project which competitions will linger into the regular season a la Knight and Bell.
Here are a few that fit the bill.
