In the States, tennis is sixth or seventh on the totem pole as far as sports go.
Monday Night Football started in 1970, and when it started, it was something extremely special because sports had not been aired in prime time. So, it was a novelty, and a lot of people thought it wouldn’t work, and, of course, it worked spectacularly well.
Tennis is not like other sports where the coach is hired by an independent entity, and that makes a huge difference in the dynamic.
I think the Cowboys are one of only two teams in all of sports that engender love and hate to that extreme. The other is the Yankees. You love the Yankees or you hate the Yankees.
