I've had time to think about it now (and I'm back at my PC, typing out reams of text on my phone doesn't appeal).
I'm not having it that the formation change caused that - before kick off the team looked much more balanced and the weird rhombus stuff just looked awful against QPR and in the closing stages against Hull; the good period on Wednesday was largely caused by QPR being as bad for 35 minutes as we were for 90 today. That is the formation we used for a year or more from Griffiths leaving to Afobe arriving and it largely worked absolutely fine, even at this level - providing Dicko was available. Which leads us on to two areas of concern.
1) Afobe. We have rarely used him as the one up top on his own in this system and today didn't look good for his long term future in that role. Yes, the service was abominable, non-existent, derisory - but as the lone man up front you have to be constantly working the centre halves, offering an out ball, showing in the channels, Afobe didn't do any of this. Not that you would ever seek to directly compare the two but it was a bit like when we had Leon up there last November with his mobility and skill of a fridge, if the striker isn't moving around then the system is intrinsically flawed.
2) Edwards. If he plays then he should only be playing in that position - everyone knows this, the manager has even directly said it on occasion (then forgotten about it and put him in a 4-4-2 or parked on the left). But he isn't actually that good at playing in that position anyway. As I said in the last couple of weeks - he doesn't create anything at all, you might get the odd one or two assists dotted around through a season (assists being an incredibly woolly stat anyway) so really you are only picking him to run around and nick you a goal. His movement doesn't really do anything other than get himself into the positions to score goals, it doesn't create space for others - his finishing and general touch are not good enough though. He had the best of the very limited opportunities we had (bar Hause's header at the back stick) and it was squandered each time through a bad touch or a poor finish. This is why his goal return isn't really very good and why talk of him being a bona fide goalscoring midfielder or getting into double figures this season is incredibly wide of the mark. By no means am I putting the defeat today down to him, he wasn't anywhere near our worst player, he didn't have a terrible game on Wednesday even. But his limitations mean he is not suitable as a regular starter for a top six chasing team, nowhere near.
Away from those two areas, the defence looked rickety throughout, Stearman is no leader at all. He doesn't organise the defence and he's always got his own airhead moments to contend with - he shouldn't have been Player of the Season last year as he basically had three good months near the end and that's it (although that is a separate matter). We desperately need Batth back, all the other centre halves look or will look fine next to him, without him and paired together they look an accident waiting to happen.
The full backs offer zero going forward and with this being the case we need to develop our attacking play in a way which doesn't rely on them getting into the final third, because really what is the point. Have them concentrating on defending.
Ken has said McDonald wasn't fit today, 70-80% in his words, don't $#@!ing play him then. We have other midfielders at the club that we could use. Coady's yellow card definitely affected his game, not that I can pin the result on anyone not connected with Wolverhampton Wanderers today but how he gets booked then Digkacoi commits an identical foul five minutes later and avoids a second yellow is the most pissweak of pissweak refereeing.
The wide players were rarely supplied with the ball, I thought Ojo provided a couple of promising moments - Edwards should have at least hit the target from one cross, Hause should have buried his header - but there wasn't much there to suggest he's definitively the answer out there. He is, after all, 18 with limited senior experience to date, is it really a realistic prospect anyway at this stage? Van La Parra took on Fabio three times and beat him three times so why on earth was he constantly checking inside and laying it back (frequently just losing it anyway with a slack ball), play to your strengths man. Don't ever let him take corners again either, amateur.
Overall, 1/10, the 1 being for at least setting out a team which makes sense on paper and doesn't resemble one of Dave Jones' brilliant tactical ideas. Much work needed.
