From my evals I've seen better but after a certain point most qbs start looking alike to me on film aside from the ones that just jump out arm talent wise
In my opinion, the biggest things to watch with younger guys are...
1. Foot work - how they throw out of 3 and 5 step drops. do they step up into a pocket (when one is there in high school)? do they throw off their back foot?
2. Decision Making - Do they only throw to a primary reciever? How often to they make the wrong/right read?
3. Accuracy - Accuracy is very hard to teach. There's only so much mechanics can do. Arm strength can be developed to a certain degree.
As far as Brandon goes, I think the kid has a lot potential to be a very good QB at a major program. He's got good accuracy and foot work and for the most part makes good reads. He's arm strength is only going to get better with time in the weight room. To me, he may be a steel for the program that gets him.
