A bigger squad than last season ≠ a full squad.
We’ve done a pretty good job with the rebuild by and large, but we look light in defence. I sincerely hope I’m wrong but we’re not going to be a side so free-scoring that we can afford to shrug our shoulders at the extra goals we’ll ship as a result of a major defensive reshuffle.
Our CBs are Branthwaite, Tarks, Keane and JOB. It looks very much like JOB is going to be first choice RB, with Coleman in reserve. Branthwaite is currently injured and seems to pick up injuries quite a bit, so we’re down to Keane and Tarks before Coleman is called upon. Even notwithstanding potential injuries (which I agree you can’t predict but you’d be foolish to completely ignore) it’s a position where the occasional suspension might well be likely.
Coleman was excellent against Mansfield but I personally would be nervous, expecting the same out of him for 5-10 PL games in a season, which would almost certainly need to include 2-3 in a row under either of the aforementioned circumstances.
Bringing in a young, relatively cheap CB kicks that can further down the road and is also another building block in creating a longer term, sustainable squad.
It’d be a decent window without one but the signing would push it into very good territory for me.
