Yes, but it's different eras. Manchester United in 2017/18 had points totals that would have won plenty of Premier League titles, many of them over their own title winning sides in the 90s, but they were nowhere near good enough to be a title winning team. Even Ole had a points total well in the 70s one year and finished 2nd, and they were fucking awful all season.
Once Mourinho/Abramavich came in then the points totals at the top went through the roof because it increased the gap between the top and the rest. Then further with Abu Dhabi and then Pep. The league was far more open generally in the 80s and 90s.
That's the point though isn't it - go back through the previous decades prior to Abramovich and then the oil state, you can drop points in anywhere between 10 and 20 games and still win the title. Drop points in 10 games nowadays and you have somewhere between little chance and fuck all chance.
Man United 17/18 were still riding the crest of the wave of media popularity and refereeing bias (they still are, just too shit to take advantage of it). They'd already been reduced to the role of also-rans since Fergie's bowel issues made it too much of a challenge to sit on the touchline for 45 minutes first half and then another 55 minutes second half dependent upon how well they were doing.
Our dropping points in 14 games this season would likely have been enough to win the title in 17 of 22 seasons between 1981 and 2003 - hardly the case that "we've not been good enough". We're just seeing the sport of football being reduced to an abomination of the game we love, due to greedy fat-cats at the top kow-towing to gangsters and nation states, where a very decent "normal" season points tally has been reduced from title winning to "hur-hur-hur, bottled it, you're fucking shite".
