Might be but will need to carry out some research on that one - didn't he take over around December time the previous season and I think he only lasted a few games into that run you quoted, before he jumped ship (according to the official site he only lasted 3 games into that season).
Mind not playing that many tricks - he took over in December 1977 and what I think I remember was the run of results from late December.
Motherwell 2 - 0 Partick Thistle
Celtic 0 - 1 Motherwell
Motherwell 1 - 0 St Mirren
Motherwell 3 - 0 Ayr United
Arbroath 0 - 4 Motherwell (and the after match shenannigans )
Motherwell 0 - 0 Aberdeen
Motherwell 3 - 5 Rangers (2-0 up and cruising and the bastards invaded the park)
Motherwell 1 - 3 Queens Park.
So in reality the 'wheels came aff the bogey' in the Rangers game.
