Most athletes think speed and explosiveness come from strength alone. But a lot of times, the problem starts lower. If your ankles are stiff, your body has to find movement somewhere else. That usually means the knees, hips, or lower back start doing extra work. I first learned about this from Coach Rick Trickett, most famously known for his work at West Virginia University and Florida State University as the OL coach. That’s why ankle flexibility matters. When an athlete has better ankle mobility, they can create better shin angles. And better shin angles show up EVERYWHERE: Acceleration Change of direction Deceleration Balance Force production Playing low without bending over at the waist When an athlete can’t get their knee over their toe, it becomes harder to stay in powerful positions. You’ll see it in simple ways. They pop straight up when they run. They round their back in their stance. They lose balance when they cut. They look stiff trying to bend. A good shin angle helps you push the ground the right way. That’s how you create drive. That’s how you come out of breaks. That’s how you strike, redirect, and recover. So parents and athletes, don’t overlook mobility work. Simple places to start: Wall ankle rocks Knee-over-toe mobility Calf stretching Tibialis raises Barefoot balance work Controlled squat holds
