Rather than a quality issue, I think it highlights the inconsistency of the other chasing teams that Aberdeen have been able to hold on to 4th. Only Livingston put together a decent run to get them up to 5th.
We have thrown away lots of points pre split, 2 at StM, and Dundee untd, 9 to the worst team in the league ffs, so 13 points at least, even taking 10 of those would have seen us challenging for 4th and a European place.
Regarding the quality of the Scottish Premiership it may not be the best but it is what it is, comparisons with other leagues are difficult as we only tend to see games involving the top sides which does not give a true picture.
