Our group used to have a tall serve and volley-er with long arms and 29 inch racquets who was 2-3 three feet inside the baseline before striking his serve. The rest of us discussed how to tell him for a LONG time cause he was a nice guy but never got around to it. However the birth of his first child removed him from our ranks and we never had to broach the subject.
