For mine it's Jacko's slow decision making that is just as much a killer as his lack of discipline. He is too often a momentum killer and in modern footy you can't afford to have players like that in your side. Players who continually can't see or ignore the first option and then either put themselves or a teammate under pressure and into trouble as a result are a liability. For someone who is apparently bright off-field, Jacko is often just a slow-thinker on it. He often just can't see the play evolving around him whereas say a Cotchin reliabily has great awareness. Combine that with his inconsistent footskills and we just need to find better footballers if we are to become the top side we want to become.
