Allen is also prone to trying to throw that route. It's why I was so apprehensive about Dorsey because it felt like he'd feed into Allen's competitiveness to make those big plays when it hasn't been his most effective route. Perhaps they are attempting to 'save him from himself', but I also suspect it's just part of the organizational philosophy that they want to control the ball and often trying these routes leads to short drives and giving the ball back to the other team.
