My initial point was directed at the multiple of posts I've seen in this very thread saying ETH deserves better or similar but yeah it's something we both agree on.
As for the bolded, that's where I think we may differ on. Considering the options available, I'm ambivalent about whether ETH goes because I don't think it's a straightforward easy decision and that's where INEOS are probably at now, hence the managerial reviews. I think the last month where ETH abandoned his suicidal 4-2-4 (with probably some influence from above), got some 'solid' results and winning the FA Cup (with a good performance no less), threw a spanner in the works from what I thought was an untenable position before i.e full sack worthy. It probably showed to them, he's not unworkable, has some redeeming qualities and I know this will be disputed, is somewhat of a 'winner', which I think is an underrated aspect not seen in the other choices (bar Tuchel, who is now seemingly out of contention).
For INEOS, who have recruited a team of decision makers, I can understand why they don't want too abrasive personalities and want someone, who can work 'under' them. So if you look at the choices, between Frank/Soutgate (shudders), Poch (now also not in contention apparently), the only remaining worthy candidate and my personal choice if I had to decide would be RDZ. I would love for us to start playing in a dominating fashion the way RDZ set up his teams but do you sack a manager (+ pay compensation), who has shown he can get results (22-23 season, League and FA Cup), risk alienating some of the fanbase when there is already goodwill because of the 'strong' finish to the season and gamble big with a fresh era? This is also after only having been in the job for 6 months where a couple of the key decision makers have not officially started yet or have been in/around the club for any meaningful timeline. From a footballing perspective on and off the pitch, it's not clear cut at all if you take all these factors into account.
For me, it's easy to see why they want to take as much time as they can.
