I think Isaac would be a fine Qb with about two years in the system learning from others. But I'm not sure he has the patience for that, and we'd need the scholarship to recruit other QBs those years to replace McCae and Trey.
I'm not saying he isn't talented, just that he isn't a superstar and he just doesn't fit our timeline anymore. He could be a good Qb for someone else, I think.
