When you’re talking about “it factor” with a qb it’s very simple. There are some guys that just flat out know how to do it.
There are guys with a strong arm, there are some guys that can run and escape a sack. None of that means anything unless they have it.
Im assuming most here have played football at some points in their life whether it be in the sandlot, high school, or even college. You knew that guy that was always qb. He wasn’t always the best player, but the best at placing a pass. Knowing where his receivers would be, take those few steps to buy time with the rush coming down on him. A lot of those guys don’t make it very far because there’s always someone faster or stronger.
Just as some guys just have soft hands and can catch anything. You can’t teach a guy to catch like that and you can’t teach a guy to have that qb sensitivity of everything going on around him.
Imo, you have it or you don’t. Mayfield has it. It’s as easy as that.
