It’s not so much height, as it is leg and arm length. Particularly for girls, tall girls tend to mean longer legs. Especially at the defender/6/7/11 position. While height gives you leverage and typically greater strength, especially in the air and set pieces, what height really gives a defender is the ability to insert a limb as a disruptive tool to regain possession or to legally obstruct an offensive player from advancing the ball. And it’s a game of inches and two inches can make a huge difference. Then you want to look at their core strength ability to burst. Doesn’t matter how tall you are if you can’t get there. Then mindset. Will she stick her head in the fan when it’s flying? All of these together gives you a pretty good defensive frame that shorter strikers with lower centers of gravity aren’t going to be able to dribble or run around. And that’s the catch right? Tall enough to defend opposing defenders on set pieces, compact enough not to get beaten by the mighty mouses at 9 and 10.
It’s like Paul Pressey. He wasn’t unusually tall. And being tall wasn’t what made him an elite defender off the press. But he did have an unusually long wing span and an uncommon and unpredictable explosive first step, even off his back foot. And a mind set to be disruptive.
Jay DeMerit, same thing. Long legs for the frame. Explosive uncommon burst from core. 100% on the mindset.
Coaches looking for height in strikers in the American girls game should be treated as suspect. That tells me they aren’t really knowledgeable or maybe interested in really coaching football. They are looking for a route one kick and run athletic contest. Avoid.
