No matter how hard you push the tackle button if they're slow dribbling the ball all your player will do is poke his toe out. The offensive player can make any small movement left or right and the defensive player will go flying past him like he can only run in straight lines. If you can change directions with the ball why can't you change directions without the ball ? You become less coordinated without a ball at your feet ? Why isn't this common sense to you super brilliant video game designers ?
Also why is the defensive player stuck for so long after doing his super toe poke ? These are professional athletes right ?
