Doubles strategies for partners of disparate skill levels?
Say you have a 3.0 and a 4.0 playing together. What formations, strategies or tactics tend to work best? Are there any simple things that the 3.0 can be taught to do in a relatively short amount of time, so that they can be an asset to the team rather than a liability? The 4.0 is fit and has good court coverage, but doesn't have superhuman speed.
