Funny I could have sworn you wrote:
If we could defend well, do the simple things well, even playing Ange's system we'd be a decent side. For example, we barely contest throw ins. Other sides make it hard for us to get possession off of a throw in. We don't. Or...we are easy to get at down the flanks. We press - but with no regard to where we are leaving spaces. We don't press with any tactical awareness - trying to force the opposition to play into areas we want. We give away free headers, time and again.
None of this comes from committing men forward. We conceded form a corner today for example - how could that be related to the way we attack? In short, we are decent in possession, the 5th highest scorers in the league. Whilst committing men forward won't ever allow us to be Forest levels tight at the back, we could still eradicate half of the goals we concede with a better out of possession shape, and coaching.
Vic also didn't cover himself in glory tonight, two goals he might have saved.
What i said in the posts you quoted do not contradict eachother.
