All 3 will be total failures? Well...there is always another recruiting class and another and another plus transfers coming in like Jaylon who I hope tears it up next year.
Believe thats why Coaching Staffs try and recruit the best possible players at every position...same reason why Heupel ended up signing DG even though he "THOUGHT" he was going to have Milton for another 2 years.
Fortunately, most (not all) true freshmen QB's do improve with more experience so hopefully DG can take another step forward as a true soph and then as a true junior and so on but if not, hope the next man/men up are even better than he.
