Great read. IMO Cassel would not rank #17 in either area if he had better receivers to throw to. Bowe has been really good, up until Sunday and Moeaki and McCluster will be good with more experiance. But for the most part all the QB's on that list have far more weapons at available to them.
IMO Cassel will be an outstanding QB for the Chiefs for a number of years to come and will improve as the team around him improves.
