Whether Broncos fans like it or not, Kyle Orton is the starting quarterback in Denver. Whatever deficiencies or faults that fans believe him to have are not enough to keep him from being the best option to squeeze the most out of this offense.
Notice the choice of words there. Orton may squeeze the most statistically out of this offense as is possible, but statistics don't always win games. (See Kyle Orton the last two seasons for reference.)
Hopes are cautiously high in Denver, and in some cases for good reason. An improved defense and running game should pay dividends for Denver. Will that help Kyle Orton match or exceed his output from seasons past?
