I think we have our QB of the future in ZG5. Looking at the stats, ZG5 outplayed Miami's QB, by far if you consider ZG5 didn't have a running game to open up the passing game.
265 yds rushing to less than 70. That's where this game was won/lost, which points to two problems.
Defense and the running game.
Arth recruited ZG5, and so far that is proving he has the ability to identify at least some talent and bring it in here. He also has shown the ability to snag talented portal transfers - Boating being the guy that comes to mind. I don't count the COVID year against Arth. To me, he's in the middle of his second year as the Akron HC. Should we have been more active during the COVID chaos of the transfer portal? Possibly. Would that have hurt the development of the young guys? Yes. There are certain things that point to "he just doesn't get it at this level," then there are other things that give me a glimmer of hope.
So, to me, the main focus of improvement (mostly going into next year since you can't make trades at the college level) is how does Arth improve the two glaring weaknesses - rushing and defense?
