A big fan of these sentences from your excellent post and something that some of those getting down on the team should consider.
A bit more context, from 2019 to 2024 in League 1 we won far more matches than we lost (with a blip through 2022-23, of course). In fact, our record in all comps during that timeframe was P273 W115 D68 L90. It's a win rate of 42.12%. We are not going to get anywhere close to that this season. I appreciate it is tricky to switch from a mindset and expectation that we should be winning more games than we lose.
Some fans need to get it into their heads that we are more likely to have a season like 2022-23 with the only difference being that we should expect to be near the relegation places this time around. Despite every player giving it their all, DB looking at every tactical trick he can pull and us preparing the best we can, 75-80% of this division will be 'better' than us - transfer spend, academy, revenues, stadiums, facilities etc. We have to play above the levels that our players are at just to get parity.
Ed Waldron said that the 2-0 win against Norwich was more intense for the players than the playoff final. More running, more pressing, more defensive blocks and concentration than a match at Wembley in front of 75,000 people. Maintaining that across a 46 game season is a physical impossibility so the falloff was always going to happen.
I sense most on here are realistic and aren't getting too bogged down in being near the foot of the table. Others just see the results and say that we're 'abysmal' and 'embarrassing'. It's natural to be disappointed when your team lose and especially when we didn't really land a glove on the opponent last night but was not 'abysmal' or 'embarrassing'. We're doing our level best against much better sides that we have to raise our levels for every match and not just for one-off cup games where we can and did catch teams unawares (West Ham in the League Cup, Newcastle away in the FA Cup).
Get out of the 'win games to get promotion' mindset and into one of 'scrap for every point' mindset.
