I'm not quite as optimistic about Schwake so far. There's loads that's good about his game, but I think he also shows his age at times. That's not really a criticism, because it's what he's here to learn (be more commanding, etc.).
The other big issue for me is that a midfield three of Grimshaw, Gillespie and Crawford has essentially zero goals in it (excluding penalties). Add that to a forward line which doesn't score and the problem just becomes bigger. For me, I think that makes the midfield recruitment not so great. The team looks like it will be solid, but a team without a decent goal threat gives itself problems because the opposition, sooner or later, figure out they can commit more to attacks without fear of being punished. In that sense, recruitment hasn't been great because there is a major lack of goals throughout the team. As a side note, I thought an aspect of this was evident when we got a few kick late on against Arbroath, just outside the box, and no-one looked like they wanted anywhere near it (until Jai stepped up and hit a tame effort).
I'm not sure how much to blame Imrie for this. I think the job he was given was incredibly difficult. And I suspect he knows the issues but hasn't been able to find the players he needs. It could be that's he's done well with the hand he's been dealt.
