100 bad reps doesn't mean you can fix it with 100 good reps to correct it because you're essentially trying to rewire the brain at that point. It becomes more like 1000 good reps needed.
Thats why its so difficult to fix certain athletic motions and skills. Hard to teach someone to shoot a basketball properly if they been doing it wrong for years. Difficult to correct a faulty golf swing. QBs that come into the NFL with a funky throwing motion and/or sloppy footwork don't typically improve a whole lot on them.
By not how it works I mean it's not set in stone forever if he has mechanic issues and plays as a rookie. There are many examples to the contrary.
