Let's let the players have time outs regardless of medical problems or not. Let them have it for the reason they often want to: to change the momentum , to gather their thoughts, take care of medical problems, and/or gamesmanship. This way, no hard feelings & no questions if somebody had a legit medical problem. Football teams take a time out following a time out to psyche field goal kickers, basketball teams take time outs to break momentum and send in a different mix of players, why not have time outs to regroup in tennis? Make them of a specific number and lenght. If you deplete your time outs and roll over on your ankle...too bad. This way a player could call a time out and tell the press later, "OF COURSE I took a time out, he was killing me out there and I had to break the momentum." Thoughts?
