I think what
@oglop44 is trying to say is the reason he stopped playing with number 2 in his back is because of his defensive failings.
All his games had been at RWB so far. If he plays RB the defensive frailties will be even more obvious. John won't make it with us at RB because his defending is so poor he is also a converted winger. I would like to see Higgins given a go there at some point as he was tried in a couple of u18s games before his injury. As Carragher said full backs are usually failed wingers or failed centre backs. The way football has gone they generally need to be failed wingers as full backs are more of an attacking tool. Mallon RB is his main position so hopefully his game is reasonably developed in both defensive skill set and attacking. Ashley Cole and Gary Neville both had the perfect balance but these types are in a minority. They also need to look at Campbell and decide what his best position is. If it's LB continue with what they are doing if he's a CB and only going to be makeshift LB they should be getting him game time at CB in preferably the u23s but if not the u18s. No point in wasting his development time on a position he might never play. I think that was part of what hindered Kenny as he played a lot of his youth team games at CB and he never grew enough so had to go back to RB. I'm not saying that's why he failed but I think it may have contributed. Connolly was another he suffered being versatile as he could do most positions to a reasonable level but was never going to be good enough in a particular position to be a starter at a club wanting what we want. Mills has recently been playing RW which might be an opportunity as most wingers what to play on the left as it allows them to cut in.
