Sanchez has plenty of arm strength and where is he now? On the scrap heap! Its not about arm strength - its about being smart and knowing what throws you can make and which ones you cant. If McElroy knows he cant throw the ball 60 yards downfield then he wont try that throw. You have to have a sense of what you can and cant do as a QB and the coaches need to design the plays according to what you can do. It all works hand in hand. McElroy will prove these last 2 games that he has what it takes but be a successful NFL QB!
