A story book career achieving unmatched heights of success. In the most recent couple of years, an obvious decline in success with one of the worst records over that span of time in the entire league.

With many speculations as to why this decline occurred from no Tom Brady to Bill being too old school, I raise the question, "Was Bill doing his job well?".
