How can a winning message of 6 Super Bowl Victories wear out?!? He can only get better at what he does, his track record speaks for itself!
I'm thinking Bart Cummings here, Steve Waugh, Mal Maninga, Melbourne Storm NRL Coach, Clarkson, these guys are Quality!
These guys would be aware of what message they were constantly putting out...self renewal would be a priority with them...otherwise these guys would not be near 6 Super Bowl wins...premierships...Melbourne Cups...et al..
New players come every year at the Patriots the message can only be new to them...
New Assistant coaches at the patriots the message can only be new to them...
I do not subscribe to...message wears out...
If you don't subscribe to it, how many coaches went out on their own terms? Who actually retired as opposed to not having their contract renewed?
