Won't be a QB.
You need to have football in your blood to play QB something a kid from Germany won't have.
Most QBs I have ever seen can discuss plays at a high level by 12-13 and grow from there.
Not all. You see some QBs who hit college with supposed all the tools but aren't able to see the field and see a play develop.
Look at Allison.
Football is feel at the QB position. You know exactly where the ball is going and you aren't going to panic
Not just because you are an Alpha but because you live, love and and breathe football from an early age.
Playing with your friends is where this starts.
