From what I saw of Carrick at a distance, I consider him to be Martin-lite. A similar style of play, for sure, but not at any cost (unlike Martin).
When Boro came down to SMS in our promotion season, it felt like Boro barely saw the ball. They were happy for us to have it. It was similar with Maresca - another possession-based manager, who decided to go it differently against us (although of course Leicester, with better players than Boro, had greater success accordingly). That sort of flexibility is something we rarely saw with Martin.
My view on whether we should appoint him is the same as what it was a few days - namely that the summer was the time to appoint him, and that I'd be a lot more concerned about appointing him now than I would have been then. I was very pro-Carrick back in May.
The circumstances are different now: we don't have a summer to build the squad and get to work on the training ground; we aren't in a position where we can risk wasting 10 to 20 games on seeing if a new manager is right for us or not; we have a fan base which is, rightly, totally disillusioned. And on top of that, we still have a squad which seems to be mentally weak and lacking leadership. As much as I like Carrick, I'm not convinced he's the guy we need at the moment. A case of right guy, wrong time?
The problem is that my own response to that view is "well if not Carrick, then who?". And that is where I keep on falling down.
