Kilmarnock have already conceded nine more goals than they did in the whole of last term, keeping just six clean sheets so far.At home, they have won six of 15 games, while their away form, which has been a struggle in the last three campaigns, has worsened with just two league wins.The 5-1 loss in Paisley encapsulated the difference as a squad that was resilient, physically up for the battle and attuned to the conditions last term turned in a limp and fragile display in the howling rain.”Every goal that was scored was avoidable from a defensive point of view,” former Kilmarnock striker and Hearts head coach Steven Naismith said on Sportscene.”If you look at the expected goals for, both teams had 1.6.
