If there are 1,000 QB's who have ever played in the NFL, there are 1,000 different examples you can use to prove any point you want. If I wanted to prove a QB needs to run a marathon before he's ready to play QB, I'm sure I can come up with an example.
My point was that up until last year, conventional wisdom was that a QB needed to sit and watch and learn for a couple of years before he was ready. If he was put in during those first couple of years, it was expected he would fail...and many great ones did at first.
But Flacco and Ryan have gone against conventional wisdom and changed that perception, at least for the time being.
