When the game is played on their terms — in their half — Carlton can take the opposition away from the game.This front-half game style forces opposition sides to fight to even get it in their attacking half. Last year Carlton was the fifth-best team at generating forward half intercepts, creating easy opportunities for repeat inside 50s. Carlton's efficiency inside 50 has wavered, but the method requires volume of entries over pinpoint entries.This pressure can create a pressure cooker for bad opposition decisions — as Demons fans saw plenty of in the first half last week.It'll often look a little like this, with Carlton's upfield defenders closing off the corridor with extra numbers and forcing the ball wide along the boundary line. Carlton also overloads the space to make the ground even "skinnier", reducing the opportunities for other sides.If the opposition pulls the trigger into the middle with a risky kick, Blues players will be there to capitalise But mid-arc contests are good opportunities to see how teams work in relatively even strength.Early in games Carlton dominates these contests — in both forcing opposition sides into conceding throw-ins or ball ups and winning them when contested.But as the game progresses the Blues get worse at all facets of the mid-arc stoppage — from forcing fewer contests to winning fewer clearances to scoring fewer points from clearance to conceding more points from lost clearances. This may point to sharp mid-game opposition analysis, a lack of variety of concepts or personnel or fatigue from those in the contest.Regardless of the cause, the symptoms need addressing if Carlton has any chance of finals.It's also worth noting Carlton's ball movement changes this year
