I love Unsy and he's done a great job with the U23's, but throwing him in in our current situation is a massive ask.
Someone like him could've come in after Moyes with us a strong team, but now isnt the time.
On the other hand, coming in from an absolute car crash like the Koeman era makes things a lot easier too. We're so low now that if he sorts out the basics, fans will be happy, or at least stay onside. Whereas coming in after the relative success of Moyes and with elevated ambitions can be trickier to manage. But, as you say, it's easier in other respects because you start out with something that basically works.
