I want to keep watching McGloin before we crown him our QB of the future, but I really enjoy him behind center.
He reminds me so much of Drew Brees. Below will be my reasoning.
Competitor - I liked watching him get pissed off when things aren't "clicking". He is a guy that will make sure his offense is prepped before game day. When he does make a mistake, it looks like he holds himself accountable and listens to direction when he comes to the sidelines. No pouting with this guy.
Brains - The common sense that this guy has showed is great. His first start, he was adjusting a play at the line. Something Pryor hadn't done all season. In order to win in NFL, you need a QB who can audible when they read the defense. Very underrated attribute.
Composure - This guy is like Brees when it comes to taking sacks. His footwork is flawless and when pressure is in his face, he is cool as ice.
Fearless - I really respect a guy who can stick in the pocket and deliver the ball. Especially one who is 6' feet tall in a 6'6 world. AKA Brees-like.
Accuracy - Correct me if I am wrong, but does this guy make some big boy throws or what? The ball placement is on target. I think he is so on target, that his WR's are going to have to use their brains when running routes finally. When he sees a hole in a zone, he throws it to the hole. His long ball is great, especially when he throws along the sidelines and to deep outs.
Delivery - He understands the concept of when to throw the ball. Some plays are designed to drop back and deliver. If it is not there, then you move on to the next play. He understands this vital concept.
These are the attributes that make Brees a top QB. There are a ton more that they share, but I'll let everyone else elaborate on skill-set. If you disagree, please let us know why.
