I can shift your thinking a little bit. First, none of the sandbaggers are doctors or lawyers, trust me on that one, speaking for TN and Dallas. The doctors and lawyers belong to clubs that often don't take USTA seriously and play ore inter-club matches, but certainly they play in level, they don't have the time to tank matches on a weekend, most are too busy working, on call etc. . Most of the self-rates are young guys in their 20s and not yet busy with families etc., nor are they going through law school or med school, or anything that takes up a lot of time. I'm casting a wide net, but that's the general profile. The captains organizing the show are usually retired and it's a hobby, like a tennis general manager fantasy league, sometimes captaining AND travelling with teams they only captain and don't even play matches on. Another category that is repeated often is tennis teaching pros forming teams, rural pros self rate at 4.0 and bigger city ones 4.5 and they bring the club members along or the people they know through clinic or lessons, good for business. I don't think you will be influenced by them in everyday life and most of them aren't bad people, just regular people with interesting behavior when it comes to recreational tennis. Why do I know so much, well, I play a lot, get recruited for teams, and facebook, when a tennis achievement happens you better believe it will be blasted on facebook.
