Of course I disagree because your post is the usual reactionary horsecrap that we are used to.
The last two seasons has seen us over perform to back to back top 6 finishes. So clearly your underperformed mid table comment is stupid. The very good collection of individual players you reference are recruited, trained and managed by Robinson. So their performance (good or bad) is a reflection on the manager.
Wimbledon were not an average/poor beatable side. They actually looked the best side we've played this season and were well organised. They also had the advantage of being at home with a fairly decent and loud home support. We didn't take our chances and made mistakes in both boxes. Robinson gambled with the subs and it didn't pay off. We can and should do much better, and we should have won the game.
But this blame game is embarrassing and is no different from when posters of the same ilk were saying that Henry shouldn't play for the club again after his handball against Wimbledon last season.
We call Wimbledon tinpot put the reaction of some of our fans on here and wider social media makes us look like a bunch of spoilt idiots.
