Jackson Irvine was excellent in the 2 2 game against us in December - I've not seen a lot of him otherwise although he seems to be highly rated by Ross county fans.
The only way he would fit in to our team is by replacing Lasley though. That could be a dangerous route to go down however. I don't believe that lasley is good enough now to be starting every week, but if Irvine replaces him and we have a poor start to the season the knives could be out for the manager not to mention the potential for disharmony amongst senior players
