It seems like people are firmly entrenched in the Brown debate, and whilst I see the point and the need for a new LB (both for squad depth and for wing back suitability), I don’t think Brown is as bad as some are making out. In fact, he’s not bad at all so I’m baffled with this debate in that regards.
Whether or not you think he’s a suitable LB would probably come down to personal preference of what you want your LB to be. Are you looking for a defensively-solid full-back who will occasionally support attacks, or are you looking for a dynamic wing-back that will look to attack more than defend?
In the former I think Brown is very good, and the latter Brown in decent. I probably think his best position would be the left side CB of a back three, or playing that full-back position.
If Seddon’s on his way out we do need another LB in the squad (we have 51+ games this season and can make 5 subs a game!) and it should be one who can play as a wing back. It’s why the debate is a bit of a moot point, whatever you think, we need a new one anyway.
