Because you move the slider if your team proves it's better than what pre-season prognosticators say. Just because we were expected to be a mediocre team, doesn't means you settle for it. KP better than advertised, Melo actually passing, much better roster depth (still overall lousy) than last years.
Look at the Mets. No one expected them to win a pennant or even make the World Series. Look at the Panthers, Super Bowl loss aside, no expert predicted a 7-9 team a year ago would be 15-1 and stampede to the Super Bowl.
It's why you play the games. At 22-22 the Knicks had just beaten the 3rd seeded Celtics and were gunning for the playoffs. If you were once good or competitive, then all the sudden the wheels come off, of course they'll be fan outrage and mass firings and shake ups.
Don't settle for mediocrity people. If the team was in the thick of things, then all the sudden lost their way, injuries or not, this team is underachieving, not overachieving. Losing 10 of 11 is what lottery bound teams do. KP, Melo, plus shyt on a stick should at least compete for the 8th seed...
