Sacking Kev wouldn't just be sacking Kev. If you want to bring in a coach who plays a back four, you almost certainly have to find the money to sign a left-back, unless you're going to stick Ralph there and hope for the best. You need to decide where GSM fits in if at all. You need to sign some wide players to add depth beyond GSM and Bridge. The squad has been built to suit the 5-3-2 shape Kev likes, and while it's easy to sit on here and say "why doesn't he change formation?", it's quite tricky to see how he would actually do that, and if he was sacked and someone else was brought in, they wouldn't be able to do anything different unless you give them the funds to do so.
Now, whether that was the right call or not is a whole other debate. It's something Stan spoke about a lot when he was involved, about a Director of Football recruiting for the good of the squad rather than necessarily to fit a specific system. But this is also what you get when you invest the bare minimum into a squad. It's true that COSU have put some money in for signings, but the likes of Moncur and Bonne are probably costing more and contributing less than other options could have. That is on John Still and his recruitment team, and on COSU for not coughing up the money earlier on.
Add in the fact that the three amigos have long-term contracts, I'd be surprised if COSU could afford to pay them off and sack them anyway. Let alone to be able to pay them off, bring in someone new, and give them a budget to work with for new signings. We've ended up paying for COSU trying to scrimp before. How many people on here knew that we needed another forward even before Cardwell left? Then we're left picking up scraps and paying over the odds for Bonne who is not good enough.
So who is to blame? The players, because there are several not playing at the standard they are capable of. Kev and the amigos, because they are getting things wrong. John Still and his team, because there has been budget wasted on poor signings this season. COSU, because they haven't strengthened the squad as much as it needs to be flexible. Ron, because COSU may well have done a bit more if they'd been in the doors earlier.
Where does that leave us? I genuinely question whether COSU would be able to afford sacking the current coaching team, and I don't see why they would be in any rush to walk. I don't think they should be either. What is clear is that something needs to change, and COSU will have to decide whether they're going to go all in and back Kev with the depth he needs. If they don't, they either can't afford to or they're trying to force him out.
