The sport has already changed massively of course, or so us old guys think, over 50 years or so.  We're still watching.
I gave up on the NFL and men's Bball, I watch some MLB still and CFB, that's it, except for curling.
I could let CFB go I suppose, but it gets tougher of course when one's team appears to be doing well.  On the other hand, the general concept of "NC or Bust!" sort of diminishes the pleasure.
