I like Dorrington, I think he's going to be a fantastic player, but I can't help but think we're making this signing for fear of missing out. We have absolutely zero requirement for a right sided centre half. He's a loanee, with zero option to buy as far as I can tell. He's ahead of Tobers and Milne in the pecking order, who are our players.
We could change to a back three, of course, but I think that takes away from what was tried last season. There are probably a handful of games where a back three would be beneficial from a defensive perspective. I'd be unconvinced of it when trying to break teams down at home (or away).
It just reeks of poor squad building to be honest. Again, I'd go back to that employee in the building who puts pressure on the manager to make sense of these calls (the technical director we were expecting five years ago). In terms of squad harmony, player development (Milne), it doesn't make sense. It's not an area of the pitch that traditionally needs a huge number of players. Knoester will likely play 40+ games, and so will Dorrington now I'd expect. We have Polvara and Devlin who can both cover for the half dozen games that we struggle with suspensions etc, I don't think we need Tobers and Milne to provide cover for that one position. In fact, as a general rule, we should be looking at two players for every position, with utility players for third cover (other than striker, perhaps, where different types of striker can adapt to different strategies). In light of this signing, I'd look to move on Rubezic (regardless of the signing) and Tobers.
