It's 100% going to be a stick to beat him with. Twice in the interview he mentioned how "competitive" the league was this season, so to then go on and "guarantee" that we will be competitive will absolutely be taken that we'll be in a title race next season. That's a stupid thing to say, even if he believes it, when we don't currently have a head coach or a squad in place as he simply can't make that promise.
I don't have a problem with Cormack in general - it's like people have forgotten that Stuart Milne ever existed when they call Cormack "a clown" and "lacking ambition" - but in our current situation the message should be that we're working as hard as ever to do better and any "guarantee" should only relate to effort levels and investment rather than outcomes.
