No.
Until we see evidence that they are going to drop points regularly to the other 10 this kind of talk is a waste of time and energy.
They won 7 games back to back between the draw with Killie and losing to Us. I'd be looking for failure to win more than 3 back to back as proof that they have lost it. Form, dressing room, belief, whatever. We need to see them dropping points to the rest.
Their next 3 league games are Aberdeen, Motherwell and Hibs. All away from home.
If they win those 3 then we will be under pressure to match them (I think they are the early kick off each Sunday). If they drop anything then maybe he has lost the dressing room.
No point getting excited about a potential timplosion yet. Its all about what we can do right now. Would love to see us go on an extended winning run now and see if they can handle it.
