I'll be honest I can't be bothered to reply to everything but I'll try be succinct.
Recruitment - it's not been brilliant, however his net spent is circa -£1,200,000. Who could he recruit for free that would have improved us? There might be loads that I don't know of, but all he could do was sign freebies and they are seldom any good.
Squad performance - well whilst we have overachieved I think it's fair to say we haven't under achieved with this squad. We scraped into playoffs last year (and how many times did Murph single-handedly win us a game last year?). so our squad has gone from finishing just in the playoffs with Murphy, to finishing just outside without Murphy. Makes perfect sense, and I imagine this squad would have gone the same way whoever is in charge.
Do I trust him - well what do we really have to go on other than freebies? What do they tell us, really? All I know is Adkins has had a year to assess the squad and who stags and who goes. Guess what happens when we sack him, new man comes in, takes all summer to assess what we have, meanwhile all targets are being snapped up and our best player gets sold 2 weeks from the start of the season, and round and round we go.
I'm not saying he's done a fantastic job, but I fail to see any certain benefits a new manager would bring. And how you can blame Adkibs for making us Ito an 'established mid table division 3 side' is bemusing considering the constraints of the board and what he inherited.
