Most collisions out on the fields are needless. Keep your ears open while you're concentrating on running toward the ball and stick to the tested formula, boys. When you shout "I'll take it!" or "I've got it!" shout it loudly and clearly. Give that signal the instant you feel the play belongs to you and not your team-mate. After that, the responsibility for the catch is yours. If you call for it, you have the confidence to play the ball, knowing you are on your own and safe from injury. The collision hazard is eliminated almost entirely.
