We need to sign a CB, not doing so would be extremely risky given his injury history and given who we have available
To be honest, I think we need to sign 2. Joel is a really underrated and good CB, when he's fit. Unfortunately he seems to have rotten luck with injuries and it doesn't help that our fixture schedule is always very congested and the league is a demanding place physically. We're coming up through a crucial period in the season, and going into it without any recognised CB's, and just Fab, Nat Phillips and Rhys Williams as well as the able stand-ins like Gini and Hendo, will be asking for trouble in my opinion.
Part of the reason that we are an attacking force is that we have such good defenders, and we have great recovery pace and ability to defend one v one with our best players. Joel, in particular, can pick a pass (as we have seen) and also carries the ball forward particularly well too, which is a big bonus against teams that park the bus. When we lose that, we also lose a bit of dynamism in attack because players can't bomb forward as confidently as before, and we lose that additional depth in distribution from the back.
