I don't get it. The Phoenix Suns only made it to the playoffs, so they fire Mike D'Antoni. The Dallas Mavericks have the best record in the NBA over the past three years, so they fire Avery Johnson. Now the Mets (who probably won't make the playoffs and don't have a stellar record and will probably be remembered for a few years for their incredible choke at the end of last year) have fired Willie Randolph. If you ask me, that doesn't really make sense. A manager/coach can only play with what he's got.
But I guess I'm old school. I prefer giving a coach a chance to learn from his mistakes and develop a persona. Look at Tom Landry. Tommy Lasorda. Gregg Poppovich. Phil Jackson. These are guys who, while they may not always be taking home championship rings, have developed personae that make their teams better. Everybody benefits when you give coaches a chance to develop, just like everybody benefits when you give players a chance to develop.
That said--I'm behind Ron Washington 100%.
