It's extremely hard to stretch the field for Weeden due to a number of things. First off you must have protection to do so, something the Browns O-Line hasn't given him a lot of. He has been very good at realizing pressure and dumping the ball off. Second, he must have a receiver that can actually stretch the field, another thing the browns are lacking. Trust me when I tell you that if Weeden had faith that the receivers we capable of making plays down the field he would "chuck" it. He has a gun slingers mentality but quite honestly, I don't think the Brown's skill personnel are very "skilled."
