So after suffering through Nadal's pokey play, as well as quite a few towel jockeys that drag on and on... What do you think of a tennis shot-clock, so to speak? That is, a clock on court that resets at the end of every point and notifies everyone how many seconds left before a warning and/or penalty. It would abosolutely force the players to play expeditiously! If time runs out before the first serve, then point penalty. Or perhaps a first-serve penalty. Has this been proposed before? Obviously support would be split for it... those who play quickly probably would support it and those who work the towel constantly probably wouldn't. Perhaps you could be more leniant, resetting the clock if there was a disturbance, or giving a player say 5 or 10 chances to run over in a match. Stupid idea, or no?
