I'm with Slink in that the over reaction is OTT, but so is the metaphorical shrug of the shoulders, 'you win some you lose some' casualness.
We aced the first half of the season with some fair to decent Championship players and some that have no right being at Molineux, however our making was the system. This is an over simplification, but for the first couple of months teams didn't know what to make of it and the next couple they were scared to play against us so often didn't try to really win the game, they either parked the bus or kicked lumps, with the odd piece of success, but were largely unsuccessful in either tactic.
Some sides still have that attitude, Preston a couple of weeks ago being one, however by and large a few things have changed. Teams have worked out we need to control the midfield so they are putting an extra man in there, they know that the wing backs are key and neither are great defensively so they are pushing men on to them, they can see that as good as Coady's distribution is he's not a career centre half and cannot cope with a physical presence on him. In summary they have a gameplan on how to win which is beyond kicking lumps out of us and 11 men behind the ball. Forest, Norwich and Fulham all played reasonable football in getting their results against us because they knew that as long as they can push on our weaknesses they could then focus on their own strengths to get a result. Ruddy's relative collapse in form is nothing to do with the opposition, but another contributory factor.
Yesterday we played the best side in the league since Xmas away from home where they've won their last 8, losing that in isolation isn't something to be overly concerned by, however the overall pattern as described in my 3rd paragraph is. I still think we will go up, but Nuno needs to see what is happening to us and come up with a plan to compensate. He's trying things like the second half formation versus Norwich and putting Afobe on to be more of a number 9, but they don't seem to be the answer.
