Whilst I agree that 3-0 at HT ends the game, the fact that West Ham were still in it gave Moyse the opportunity to change things and his tactical changes worked.
Coufal was very tight to Johnson first half. As opposed to Emerson drifting forward more and allowing Kulusevski room. WH changed this second half doubling up on Kulu. West Ham also played into the spaces between our CB’s and FB’s more second half - something that’s been really noticeable live as opposed to on TV.
Moyse probably delivered a huge bollocking at HT and I suspect a parting message that they could get something out of the game if they pressured us. They came out 2nd half with a noticeably upped tempo compared with our noticeably lax one.
Tbh the warning signs were there before the Chelsea debacle where we enjoyed the rub of the green more often than not.
The inflexibility is a worry because Angeball has been sussed out. In particular, if we don’t score a hatful of chances in the first half when we are flying, teams will exploit our predictability second half - Villa, West Ham and to some extent Wolves are cases in point.
One last point is the Harry Kane sized elephant in the room. He’d have scored at least a dozen goals in this system by now and we’d conceivably be top or thereabouts. The lack of a finisher in Ange’s system is killing us
