Actually yes they do. If you're not comfortable u won't be confident. If you're not confident it will throw every aspect of your game off. Same thing with a shooter in basketball. Once they get hot and their confidence builds it's hard to miss. It's like Curry turning his back before the ball is even in the rim. He is confident it's going in.
Yes all 3 are learning a new offense but the other two has chemistry with their teammates. Idk if you've ever played a sport but u have to earn the respect of your teammates. If u earn their respect and become their leader the lineman will block harder for u, WR will run a route harder over the middle bc he knows u wont set him up to get layed out.
The battle will be won this summer. The other two QBs have shown they have character issues in the past.
