Last year the Red Sox had their greatest season ever. This year they will not make the playoffs. I am not paying much attention, except for the batting statistics.
I don't want to be greedy. After an entire childhood and middle-age of only the Celtics winning championships here and there, we have had unbelievable riches in New England since 2001. In addition to championships, we have had many "almost" seasons that other regions would be happy to remember.
We are lucky in that we have so many colleges that only the alumni of each one cares about its sports teams, so the fandom looks at the professionals. We have only FCS football, occasional NCAA tournament basketball, laughable college baseball, track-and-field, etc. We do have good college hockey, for what it's worth.
The Celtics fell apart. The Red Sox have fallen apart. Never count out the Patriots, but Kansas City, Los Angeles X2, Indianapolis, Carolina, Philadelphia, Minnesota, and a few others look good. The moving finger writes, and having writ, moves on.
