Were you there on Saturday? Genuine question, because if you were, I'd love to know which Taylor you were watching. The goal was only one of the many many times he was caught out at fullback.
But he isn't a full-back.
Solano, Duff and Pancrate have had games at full-back for us in recent years and were better than Taylor's showing against Everton. You would argue that playing CB and moving to RB is perhaps easier a transition than moving between full-back and winger, as Simpson showcased nicely for us at the weekend.
Ffs - he had a bad game. In the past he's had some pretty good games out at RB and indeed LB when he first started playing. That didn't make him a great defender, no more than a bad game on Saturday makes him a crap defender.
