Ummmm, excuse me boomer, but i have never been under the assumption that Big Ben was a "mobile QB". somethings just seem to come out of the air for i dont know what reason. Your bias is preceding your true gut feeling IMO. The similiarities between the two are that they are teachable and understand defenses and how to expoit them. In other words, they let the game come to them. They react to what a defense does very well. The differences to me is that one is more durable (Ben) and broader and takes what a defense gives to him and tests them downfield every once in a while. Orlovsky is more Like Phillip Rivers in that he loves to throw the ball and goes downfield often. Orlosky can run the ball too, its just that he will stick in the pocket looking for the downfield play more.
