Where is this myth that Boly hasn't been good at RCB come from? Between his return from injury and up to the Arsenal game he was impervious, and the stats back that up, we barely conceded a goal with him there, he hasn't looked as good on either side since that game for whatever reason.
Doc is a WB not a FB, he and Jonny are fundamental parts of how we attack (a goal and an assist between them last night) so yeah, they aren't always going to be exactly where we would want them to be defensively, especially when we are being counter attacked or if we give the ball away, but that is exactly why we have 3 at the back, to cover for that eventuality, I think you'd struggle to argue that Doc or Jonny have been out of position and cost us (m)any goals this season? Throw in the fact that Doc scores goals, is good in the air, has a good attitude (now) and never seems to get injured i don't really understand why he is constantly one in game mistake away from a pile on.
I'm pretty sure that if Nuno had signed Doherty a few days after his arrival the opinion of him would be entirely different, the fat and shit stigma he justifiably acquired prior to Nuno's arrival still follows him around now and means that he is under rated and under appreciated by many Wolves fans.
