I'd do what we are doing - that doesn't mean it's good, it just means it's the best of a bad set of choices, given that we have a finite budget (and an infinite squad

).
For now, for me the worst/weakest aspect of the team is probably defensive midfield, and on occasions it really is very bad, but the task in hand is to manage this with the resources currently available.
It's been pretty clear from the outset that the plan is to outscore the opposition.
I think Adkins' framework includes:
- invest available money in goalscoring
- get the team well organised in order to defend - this has probably worked best at Swindon and (league leaders at the time) Burton
- work on set pieces - improve players collectively
- improve players individually
- bring outcast players back into the fold, and thereby have greater reserves to draw on
- assess how the squad play under his management before deciding on where to allocate limited financial resources
- assess the impact of players returning from injury
I agree that 2CHs and 2 CMs would be great and almost guarantee us promotion but I'd estimate the cost to be at least 4 x £1.5m, possibly more. This is unrealistic.
As posted elsewhere the Murphy money is a significant issue; there are questions that need answering about why it hasn't been spent. And by questions need answering I mean just that, not: It's bloody obvious and the Board are crap.
Everything I see from Adkins makes me think he really knows what he's doing - and if he can't get us out of this division then we could be here for a very very long time.
He knows the big picture inside the club (and inside the League) and, for me basically, his experience, skill and judgement are dictating who plays and how they play. It'd have to be an extremely strong argument to make me think Adkins isn't doing the best for us long term, I haven't seen that argument yet.
