In Readings first season, although he was defensively not great, I thought his passing and crossing were pretty good and if he had been able to work on the defensive side of his game that we would have a good player. However, and probably due to us playing hoofball since Kerr left, his attacking side has deteroriated significantly and his defensive side hasnt improved (got worse?).
A change of scenary may be what he needs to jumpstart his career, and you never know a break over the summer and some coaching we may still see a player, but probably not
Edit to add if we had ever gone with 3 CB's I think that would have seen us getting the best out of both Houston and Raading, as both were never great defenisvely but had a decent range of passing. However last season especially wouldnt have suited us in an attacking sense as we had decent wingers at the start of the season in Mullin and CHalmers
