All three of them were either too flawed, too careless, or too streaky to be relied on to win games consistently, let alone shootouts.
Ian Book was the only QB Kelly produced worth a damn and Kelly should owe a royalty fee to Book from his big payday, as the only consistent stretch of winning Kelly displayed in 12 seasons were the four that he had Ian Book as his starter.
Kelly was kryptonite to good QBs...think about it, what was Kelly's base for being a QB coach? ..because he played LB and tackled QBs, or because he read a book about it one time?
