Fully understand what you are saying. But there are loads of factors to take into account.
Fitness will still play a part
Any knocks/injuries too
Then any tactical implications that NW is trying to mitigate
But I do agree with your last point. Anyone not showing the correct attitude needs shifting out
We have so many midfielders why not go with a straight 4 - 4 - 2. It offers a defensive role for our back line and not so hard to understand and maintain formation. Well as long as the wing backs don’t get caught out to far forward and it offers support in attack. We have nothing to loose, so why not..
