it is funny same was said last year about Petty... time of when a quarterback could be ready to contribute is never the same, but what we saw from last year when Petty played to what he did this off season, pre season in his development showed one thing the new coaching staff knows what they are doing... come next off season, pre season will be key if Hackenberg can take the next step... depending on what level he improves too will be the deciding factor if Petty is still on the team next year and moving on...
I for one want to see Petty get his chance, but age and longevity at this position is also a plus when Hackenberg is still only 22 years old, his potential is still there is because of his age and the team is in no rush to march him on the field...
