Stats can be manipulated to support any side of an argument. If you compare like for like and compare Millen's 12 league games at the start of the season with McInnes' last 12 league games (or our current form, if you prefer), the results are much closer:
Millen W1 D3 L8 6pts from 12 = 0.5/game
McInnes W3 D2 L7 11pts from 12 = 0.92/game
Projecting our current form over the 15 games remaining gives a return of 13.75pts (let's be generous and say 14 points)
That's only a total of 45 points and while I think that may probably be enough, I'm still of the opinion it will go to the wire. I think a lot depends on whether McManus can improve our form and patch the defence to concede less.
