Flash in the pan QBs!

So I noticed the thread about Jalen Hurts. Seriously, I never watched one second of an Alabama game so I had no clue who he was even. The tide insert an unknown and he delivers like the next Joe Namath. Now the same thing happened for pitt starting a new QB against Miami. For anyone who has coached or played at a high level, can the lack of film/preparation against one player, especially the QB, be a factor here?
