I recall the anecdote about how McD was let go in Philly. He was replacing the late great Jim Johnson as their DC. A really tough act to follow for a young coordinator. Upon letting McD go, Andy Reid had told McD something like ‘I’m doing this for you.’
That has to be playing in McD’s mind. Another young coordinator that’s replacing someone that, while not legendary, has certainly had success.
Of course, McD must also be considering that Reid himself was let go not too long after.
