What are you missing? Basic reading comprehension by the looks of it. I'm not "looking to absolve the manager of all blame for quality of the players" he's brought in, and it's mad that you've somehow got that idea. I'm simply looking to provide the much needed context to whatever criticisms people want to make about those players.
Your stuff about whether he's the man to take us forward is completely irrelevant to this specific discussion, but again, you're clearly lacking comprehension if you can't see that there aren't many people (myself included) that are more than happy for him to get the boot, whether that's soon or at the end of the season. However, the reason they're happy for that to happen has nothing to do with his shit transfer record (which was the topic of discussion here, and that shouldn't have been his responsibility anyway), and a lot more to do with the other points you've raised. Points that are often ignored in favour of wailing incessantly about him signing Antony and Weghorst.
I'm actually more than happy to criticise Ten Hag for how little he's managed to get out of Antony, especially given that they'd worked together before. Similarly, I'm happy to criticise him for how often he expects Casemiro to cover half the pitch on his own, and even for how Mount appears completely unsuited for the role we apparently bought him to fill, even if we've not seen that much of him. Importantly, these critcisms can't be made without the caveat of how these players came to the club though, and that's a massive fecking caveat.
I'm not sure if you did and I can't be arsed going back to check, but people keep banging on about transfer fees, as if this is Football Manager and Ten Hag's the one sitting down negotiating these deals himself. The money spent has nothing to do with him whatsoever, even if some of the players were his recommendations. Simply put, the club shouldn't be giving him first choice of his own targets anyway, and even if they are, they certainly shouldn't be paying well over the odds for them, just because he wants them. Again, I don't care if he's sacked tonight (even though we won), but it's very hard to trust that the people who desperately want him gone now won't be equally as toxic with whoever replaces him, when they're constantly using stuff that's got feck all to do with him as a stick to beat him with.
