This response from a question asking about a QB change from the ask TD page
Whether it be the quarterback position or any other position on our team, Mike Mularkey believes in competition each year regardless of what has happened the previous year. You have to start from zero, and players have to prove that they are worthy of the position. At this particular time I really can't tell you on specific positions what is going to happen, but it will become obvious as we begin our off-season planning and strategy.
