US Patent 7993221 Lacrosse head with sidewalls of asymmetrical height

A lacrosse head in which one of the opposing sidewall portions is shortened by bringing its lower rim upward relative to the corresponding lower rim of the opposing sidewall. At the same time, the upper rim of each of the opposing sidewalls is maintained at the same level. This moves the pivot point of the shortened sidewall closer to the player's hands and allows faster clamping when facing-off. Faster clamping likely results in an increased number of “wins”, or possessions, that occur after the face-off.
