Yes, he did try the high-pressing game, albeit with slow defenders with Ferdinand and Vidic, which was why we didn't do well with this. If he played a duo from Smalling, Jones, and Evans, he would have been able to play the high-pressing game because the 3 latter defenders are faster than Ferdinand and Vidic. However, injuries affected this implementation, hence why he resorted to sitting deep, being solid, and keeping shape.
If Moyes was a competent manager, he would
[balance] our weaknesses and strengths.
Why hasn't he balanced them out? Why doesn't he play to the strengths of his players? Great coaches, regardless of what players they have, always find a way to amplify the strengths of their players and attenuate their weaknesses. Moyes hasn't done this, so far (why would he play slow defenders in Ferdinand and Vidic in a high-pressing system in the first place?).
We need better quality players and if you see lower down the league such as Southampton, Swansea etc they have more overall quality than us. Why? They are able to do things we can't as showed above, even if they cost so much less to get those players.
Both Swansea and Southampton have worse defenders, goalkeeper(s), and forwards than we do (midfield is debatable). It isn't the quality of players that's making them play better than us, for sure.
At Southampton, Pochettino gets the best out of Lambert and Rodriguez by setting up his team to cross the ball into the box at every opportunity, thus playing into the aerial strengths of Rodriguez and Lambert. Swansea is a good example of how players weren't played to their strengths. Laudrup always played Jonathan de Guzman in central midfield when he's best as an attacking midfielder. Bony couldn't fit into Swansea's short-passing setup, so Laudrup had to set up a more direct, crossing style to bring the best out of Bony, which didn't bring the best out of the likes of Britton, de Guzman, Routledge, and Swansea's Spanish recruits. One of the reasons Swansea struggled at the beginning was because the likes of Shelvey and Bony didn't fit into their short-passing style of play and were better in a more direct setup.
All of that aside, it is important to play to the players' strengths and not just be stubborn and play one way like Villas-Boas has done, so far, if the players aren't available. For Moyes to set up a strong Man. Utd., he either needs to get players in who will fit into his style of play or play to the players' strengths. If he fails to do either, then we'll continue to struggle.
