(Not to draw your ire PhD, you're just the messenger - I get it)
BUT Myles states "3 playbooks in 3 years" implies that he had to learn 3 in 3 years. Uh, no - the Air Raid O he had did not change much from the prior years. Learning Boras' system was tough, especially as they force fed him everything at once, but McVay intentionally made it easier for all Rams QBs to learn through his process and methodology.
So to to just throw our a quip of "learning 3 playbooks in 3 years" does a disservice. That's all I meant.
