People who remain confused seem unwilling to accept 1 possibility: Shelley is a better QB.
If there’s mop up duty, wouldn’t you give it to Shelley since HE is the better QB and you don’t want to risk SHELLEY transferring? Why would you even be thinking about the 3rd string kid?
Also, it’s entirely normal to only take one QB in a class, because that guarantees the kid reps. Schools fudge that promise by taking another QB as an athlete (how we landed Shelley while recruiting other QBs) or offering another QB a gray shirt opportunity like we did with the BYU kid.
