I don't want to move this conversation too far away from Conor, but I was looking back through our full backs from recent seasons, and there aren't many good ones, or least, few that have universally been appreciated.
Before Townsend and Furlong we had:
Gibbs - some would say lightweight in the tackle and injury prone
Ferguson - generally well rated, but left under a cloud
O'Shea - out of position and didn't offer much going forward
Holgate - generally well rated
Nyom - very up and down
Tosin Adarabiyo - out of position and not rated
Dawson - played out of position by Pulis, not good going forward
Brunt - played of position by Pulis, not enough pace
Gamboa - not played a lot
Pocognoli - not played a lot
Lescott - out of position by Pulis, a lot of ups and downs
Ridgewell - very up and down
Going back further you have the likes.of Billy Jones who people used to criticise for being a poor defender
I suppose the point is, either we have had fairly poor full backs for a long time, or, fans expect too much from full backs, including the likes of Townsend.
