Great picture, but I noticed something...
Look how RW doen't have the ball tucked away properly. The bottom of the ball looks positioned under that massive bicept right, but his fingers aren't wrapped over the top point of the ball as they usually show is correct.
You can see how if he was hit from behind or at the wrong angle that the ball could squirt out.
I would say that RW is probably the best player on our team, but correcting fumbles is one part of his game he could still work on...
