I remember KOH being stretchered off after a really serious head knock. Might have been in the game against Dundee that got us in to Europe. Not sure though.
You need to appreciate that RandomGuy has done extensive research on this by watching some highlights in Saints TV.
He has extensive knowledge of any football matter you care to mention including Falkirk's youth academy (in particular the career of Kevin O'Hara) and this knowledge even extends to the managerial techniques of Nigel Pearson and his penchant for falling out with certain players so he could show his authority in the dressing room
Maybe Scottish football is better than some people think. Doing okay in League 1 doesn't necessarily mean he's good enough for Saints.
As for the "best position " rubbish, it's up to him to fit into a system.
