when those before him were not doing well at the QB position.
Jurkovec is still learning and the longer he stays off the field and learns in practice, the more advantageous it will be for ND down road and more importantly, him. This OLine isn't doing all that well and until it gets better, it might be best to keep those guys with experience out there - at least they have the build to take the punishment of being hit.
This is not saying, BK will coach him to be a better QB but it certainly is clear, Wimbush's only issues are, accuracy and touch - other than that he's a 5 star guy.
