The same impact any forward has made...For a forward to score goal of have an impact on a game, the midfield has to occupy the opposing team defence, means the defence has to have the ability to start an attack. KJ, Cornell glen or a young Stern John, cannot have an impact by themselves. When every player on the team, goalie included (hoofing ball down to glen,surround by 3 men, who could foul at will) , can havean impact, and not just on the field to defend, but also attack, and draw opposing players, then KJ or any single frontman, can have an impact. I thought this was an excellent demo by Peru of this, everybody with or without the ball, was dangerous on attack, yet when they defended, they were prepared to counter, it when they were more dangerous. This was, and still is a big football country & team. They play in one of the most difficult groups in the world, regularly. We did well for a nobody team, with unsure future picks. We need more lessons like this. Yuh doh go one class in chemistry( or anything) once a term and become a doctor.And even when yuh study for years, practice for years, yuh could still lose patients. Don't lose patience on a small country team football game.. Players, coaches and fans need to study and work harder is all.
