You do understand the complete ramifications (for the negative) of changing coaching staff mid way thru Allen's career?
I'd think he gets his choice of assistants. Which means new schemes, etc. Which then means new personnel needs to be drafted or traded for. All of this means TIME. Our personnel currently fits the schemes we are playing, in all three phases.
This isn't the best idea given Allens limited career lifespan. It's just not as simple as "lets fire the coach!"
McD is a very good coach. I'm sorry he isn't 17-0 each year, but changing out would be a total and complete waste of Allen imo.
