Jack Ross' most successful period in management was with St Mirren in the 2nd tier of Scottish football.
For me, it is absolutely no coincidence that the upturn in our form under Ross featured the arrival of Steven McGinn. McGinn was a leader on the pitch. He was passionate, committed, and provided coherence. That was at least as significant as anything Ross contributed.
Without McGinn, St Mirren would have been relegated. Without McGinn, we would not have won the league the following year.
Oh, and there is the small matter of Lewis Morgan being the best player in that division by a considerable stretch.
To a great extent, the stars aligned for Ross back then. His biggest mistake was not cutting his teeth in the top league with Saints. He believed the hype, and it has backfired spectacularly
