KF has been around forever and has had players come and go the whole time. Other coaches all have a good idea of the gist of how Iowa does things. Their aren't any KFC recipe level secrets being kept under lock and key. It's hardly an advantage if Boyle relays to his new team that Iowa on 3rd and 7 likes to run a screen pass or draw... We aren't curing cancer here just playing football. To be petty with a former player that's done nothing wrong but compete for 3 yrs and graduate is just wrong. Maybe he felt guilty by not giving him a real shot at playing QB...One thing about players from another team is they have inside knowledge on how you do things. It can be a pretty big disadvantage.
