I dont think there is enough time for him to run back to the middle after a goal.There seems to be an absolute determination from the coaches not to play Lyons in the centre square.
It reeks a little of the Craig/Walker dynamic.
Lyons can do some things well, other things not so much. The coaches seem to be trying to make a point with him - not let him just play to his strengths but to overcome his perceived flaws.
I reckon coaches box themselves in with this attitude. If Lyons plays in the guts tomorrow and gets a ton of clearances = Sando you idiot, we could have had that all along. So he won't. No one likes being shown up. Same if Walker kicked goals for Neil without doing all the other stuff Neil valued so highly. That's cheating! So we stick with forwards who tackle but can't kick a goal to save their life.
I reckon we are cutting off our nose to spite our face.
