What next at Ibrox and Celtic Park?
A really good manager can address all of this in relatively quick order, which is presumably why Celtic are waiting for Howe. If they think he's the guy with the nous and the charisma to spark a recovery then they'll feel it's worth taking some flak from annoyed supporters in the short term to get the benefits of his management in the medium to long term.
Celtic will see it as holding their nerve and making the right appointment, but Howe, if and when he arrives, will have some amount of expectation on him. We can't know if he fully realises what it's going to be like or, even if he does know, how he'll deal with it, but two minutes into the job he'll realise he ain't at Bournemouth anymore.
It'll be interesting to see what Rangers do in the summer. The club has already stated that they'll need to sell an asset or two to address the finances, but how far do they go on that? The champions of Scotland next season gain automatic entry into the Champions League group stage. It's a £25m season. Maybe a £30m season.
Celtic have a bewildering array of decisions to make, but Rangers are not without their own puzzlers.
If somebody comes in strong for Ryan Kent, Glen Kamara, Filip Helander, Barisic, Morelos, James Tavernier or young Nathan Paterson, do they listen or do they slam the phone down? They have to walk a line between selling a player or two in the name of fiscal caution and keeping them all and adding a few on top in the name of ambition and evolution and that pot of gold that awaits the 2021-22 champions.
Gerrard will push for more resources as befits a manager who demands constant improvement. Having taken so long to knock Celtic off their perch he will want his club to stick around at the top for a whole lot longer than one season.
Watching how Rangers balance the need for footballing progress and financial prudence will be interesting. The months ahead will be dominated by the remaking of Celtic, though. The revolving door hasn't started whirring yet, but it will. And soon.
Rangers' rise and Celtic's fall was starkly illustrated on Sunday as the visitors were swept aside at Ibrox, writes Tom English.
