I think the connection between those two things is looser than a Leon Barnett backpass; Ruddy hasn't been put off by any of his other few mistakes or by not keeping clean sheets, so I can't see him loosing sleep over the Ramirez challenge either, and as long as Lambert puts faith in Ruddy, Ruddy will be confident.
I am not categorically saying he is scared, I just have a hunch after watching that particular incident. Just appeared a little hesitant. We know crosses are not always the strongest part of his game but maybe, just maybe now we are experiencing much more pressure from strikers than we have endured in the last 2 seasons another slight weakness in his game is being exposed?
I think that save he made at 0 - 0 from Bent, when he made himself big after Bent was clean through, showed us that he lacks nothing in the bravery stakes, I think he was just unlucky with the back-pass situation, on another day the ball could have gone safe
