I think Critch is being afforded more time because this has been sold as a longer term, sustainable project where players will improve on the training ground and lead to success on the pitch, hence hiring someone super qualified (in terms of his coaching badges and work at Liverpool).
Whether this project will ultimately be successful remains to be seen, but the very nature of the plan requires time and patience to allow it to come to fruition. An inexperienced coach working with younger players will encounter problems and see ups and down, but there has to be some sort of improvement over time. We clearly got that when we went on that run, but since then we've struggled and it has been a bit of a disappointment ever since.
With Grayson, who I thought was potted a little too quickly but could understand the reasoning why, it seemed to be the plan to try and get out of the division by making a few signings after hiring arguably the most experienced manager available to achieve promotion from League One.
The football was turgid, and whilst the goals/points tally may be in Grayson's favour, I would imagine most of his points were picked up earlier on in the season whilst we were doing ok, before it tailed off in to an uninspiring mess which led to some of our wonderful fans having seen enough and calling for his head/abusing the players
We have to start getting back to winning games, which will only come through creating and taking chances. Half of the season has now passed, we need to be seeing more than 75 minutes of possession with sod all to show for it except 1 goal if we're lucky, a raft of substitions that have zero impact, and then 15 minutes of huffing and puffing. Every game recently has followed that same design.
