We've been told that the summer transfers were discussed as early as Oct last year so the DoF is essentially irrelevant this summer.
The point missed in the context IMO was the significance of the season ending injuries, and the change of shape the necessitated to return of the players previously on the outer, and even more so when Rambo was ruled out as we lost his non-stop work rate as well as his big match performances.
That said I agree that Emery and the new structure should not be immune from criticism, however that criticism and the decisions made this summer should be made in relation to the original intent and objectives behind Emery's signing. To that extent I think they are thinking along the lines of a 2 year plan to regain CL either by PL top4 or more likely via Europa (given the cluster f*ck our finances are in), after which if that has not been achieved then the squad will be gutted and we move on to plan B and a longer time frame (at which point I do not think the club will extend Emery beyond the initial 2 season deal).
At this point whilst we are still on Plan A I do not think the quality / aesthetics of the performance is important as the aim is to regain CL - nothing more and by which ever means we can. I also think that our top4 challenge was somewhat unexpected and actually worked against us as it meant we could not focus on one or the other. By this I mean that the reality is that the squad is not top4 quality as every pundit said throughout the season - if anything the top4 challenge has also worked against Emery because of the way we fell apart in the run home. Even so IMO the collapse at the end of the season was little different to our previous annual collapses during the 3 week window in Feb-Mar each season under AW, including the relegation form shown after the CCup Final loss to Brum.
Only once we have regained CL do I think that the performance becomes an issue as a big part of the success of plan A relies upon doing so with much of our current resources. However if we need to go to plan B next season then the performance needs to become far more important as we transition the squad, and I suspect Emery's pragmatism will not provide the long term product we want to become identified as.
