100% this.
For me one of the reasons McLean got sacked, Whyte was a complete passenger in midfield, and in effect we were starting 4 Centre Backs last night ! Could see the difference in the middle of the park when Scullion came on, after that we started to control the game in midfield.
Fact that everyone can see that apart from McLean and Millar is worrying, we need to get a manager in that actually knows something about football !
