For: The player who struggles with hitting the ball fat, hitting the ground first and suffering the wrath of greenkeepers everywhere.

Drill: The worlds top players very rarely take deep divots. They tend to "pick" the ball off the surface. If you have ever been told to keep your head down in an attempt to keep your eyes on the ball, you may be struggling and hitting the ball fat. Try practicing hitting shots, taking your eyes off the ball just prior to impact, a la David Duval. This will give you greater freedom in the downswing, leading to solid contact and more healthy looking divots.
