Well I don't think any clubs' owners would come out & say "we'd happily settle for 6th place" in a ten-team league. I'd be quite happy to stay up but I don't think there's much between the teams outwith Hibs, Falkirk & yourselves & given that 2 out of those 3 have new management teams, I bet AJ & the board secretly harbour ambitions of the play-offs.
I heard that Leishman interview & I'm fairly certain he said we have a top 6 set-up in place, which is arguable if he was talking about the stadium etc. I'd agree with you & stats would support it - in my time supporting the Pars (30-odd years) we've never been an established anything, apart from a fair size chunk of the noughties which was all built on sand of course...........
