Players should take responsibility and be out pounding the pavement & hitting the gym during the off-season (Oct/Nov/Dec) and turn up fit to train come pre-season. That would allow the coaches to put more time into skills, tactics and match specific training during the pre-season instead of having to whip 3 months of booze out of people in 4-6weeks. Second to that teams at the top level should be training 3x a week + a recovery session but that is a whole nother story.
