If this is your main gripe, get comfy banging that drum for the foreseeable. My inference would be that Garner sees it as we're perfecting something, rather than trying to do something we can't.
And fair play to him for having a vision, a big picture, a philosophy and sticking to it. I respect that he's got the courage of his convictions.
Hopefully it's short term pain for long term gain.
This is why I have a thought that he will eventually not make a good Manager but instead find his way into Senior Academy work, or Technical Director type roles in a big club.
He has a lucky mix right now of a club that is generally a good one to be at in League 2/Div 4 based on history, was in a sad state and willing to invest in youth/younger players and a longer term burn (for now).
His tendency is clearly towards coaching/development of players around a style/approach he has become wedded to through his Academy and youth work to date. It is showing already - we have a very clear structure and method of play which is designed to work with players who are focused on technique, possession of the ball etc. You don't really want too many journeymen in that type of team, and it fits quite well with picking-up Academy prospects from above us that don't quite hit the grade, or loans that are not quite ready.
I'm not suggesting that won't work for where we are right now, BUT, it does rely on 100% commitment from everyone in the club to keep picking up that talent. Crewe have shown they can bob along between L1 and L2 doing something similar, Garner may be able to push it a bit higher with us. Long term though, I think he would happily sacrifice a few wins to develop the talent, and our history suggests we are far from stable and having a fanbase accepting of such cycles of development, as are few clubs.
His record at Bristol Rovers should not be ignored - he saw that as a project and not a failure. Imagine us getting the results he had at Rovers playing this way and with an ownership team a little more at ease with the clubs financial situation.
Long term he will come a cropper and find few clubs willing to invest in five year + projects at anything above their Academy systems.
For now, the clubs ability to pick up players at a decent enough level in League Two means the fit is working well enough, and with the right adjustments in January we are a good bet for being in the hunt this season, so it is a problem for a future date. In the meantime, I don't see any evidence that things at home will change that much, equally, no reason we can't continue to do well away.
