As writers go, so goes the show. If the Scrubs writers left, you can count on it starting to suck. The same thing happened to the X-Files, which started very strong and ended up turning into crap seemingly overnight. It's also what's happened to Lost, I'm told (I've only seen DVDs of the first season and a half, so I'm bummed that Lost has lost it). Apparently one of the main producers bailed.
