Same as it always will be. If that's not neat enough, if that's not nifty enough, if that's not 'now' enough, so be it. Tennis doesn't have to reinvent itself to be great. It is great. We do not need fireworks at the changeovers to be exciting.
Tennis is long rallies, touch volleys, and lunging overheads.
Round robins and public courts. The genius of Pete Sampras and the spirit of Tim Gullikson. Tennis is tennis. And that is more, much more, than enough.
