When Costello gets hot, he can deliver the ball as well as anyone in the country. He's a big, strong kid with a ton of arm strength and the ability to fit the ball in to the tightest windows.
Costello is accurate to all three levels of the field- short, intermediate and the deep ball and understands when to take a little off and when he needs to put a little extra on it. He anticipates very well and when he's in rhythm, throws on time and decisively.
Costello will throw an occasional interception, usually a result of holding the ball a little too long and then throwing late in to coverage. He has a very high football IQ and understands the game well so we're confident this won't be an area of concern down the road.
The Stanford commit is also a highly competitive athlete and is all about winning. He shows natural leadership skills and has already made a big impact as a recruiter since he first committed.
We would like to see him continue to improve his overall athleticism and mobility in the pocket. Costello won't ever be confused with Michael Vick, he's a pure pocket passer but if he can improve on his escapability in the pocket and making that first man miss, it will definitely make him a more complete quarterback at the next level.
Here's our breakdown of what we saw from Costello at The Opening last week following the event.
