I think we need to remember that the team are still coming together...that front 3 have never played together and Slattery is only playing his 2nd game up here, and playing beside a guy who has had a full year out on the treatment table. I wont be making any judgements until we've played at least 10 games.
In contrast, St Johnstone have a settled side and theyve been settled for years now. Wotherspoon, Craig, Davidson, May, OHalloran , McCann all played for them for years and theyve a very settled defence as well. Won both cups and just took a draw away to galatasaray...they're a good side.
That said, I hate the formation we play, 3 up front with no real width and players that dont look comfy playing wide of a striker...the midfield 3 are so narrow and that will only work if the full backs are competent going forward...which I'm not sure they are.
