I agree with so much in the OP but I cannot agree that Clarke and Sharp have not got good movement. Sharp has always been an active player and Clarke always has when he's played against us.
When the opposition take us on and there is space up front both players are always showing for the ball. However it has become a trend that the opposition are giving up the midfield and forming two deep banks of defenders. That changes the whole dynamics and I'm afraid we respond to that with a slow, predictable buld up which features Fleck and Couuts taking an age to pass a slow ball out wide. Freeman on the right does try to build something but he's not a winger who can get to the bye-line. Lafferty on the left offers nothing much at all, in fact he's at his happiest passing the buck to O'Connell who has far too much crossing to do ( from way out) for a defender, normally a centre half.
Only late in the game that's not going well does Coutts enter the final third of the field and I must say that Fleck has disappointed me since the Bradford game when he was outstanding.. That slow build up, always across the faces of the opposition, usually out to a non-winger must really piss off any striker, probably to the point of just accepting that the service when it comes will be a long, high cross from deep, way out wide.
This is a nightmare scenario for Sharp who hardly competes in the air for high crosses. Clarke too is not a conventional target man, he's not just a battering ram, he's got a deft touch and plenty of skill. He competes hard in the air but the opposition give him a hard time in a packed penalty area and he's the sort that doesn't get much sympathy from referees therefore he's cancelled out.
