For 24 hours, the NBA had no head coaching vacancies. That's a stunner for the week after season's end; usually there's a bloodbath immediately following the final regular season game. But Flip Saunders quickly replaced Ed Tapscott, Oklahoma City hurried to lock in Scott Brooks, and the other potential openings remained tentatively filled ...

... until the Kings declined the 2009-10 option on interim coach Kenny Natt's contract Thursday. The move had been expected with some certainty. But in comments related to the new opening, Geoff Petrie has raised some eyebrows about what kind of coach the team will seek.

The Rotation is a weekly study on the NBA by one of our All-Star voices. In rotation this week is Tom Ziller.

An annual tradition regular as daybreak, as the season ends a pack of coaches are mercilessly hacked to pieces by fans, media and often their own bosses. A parade of potential replacements jumps aboard the carousel. They dance, they preen ... one of them wins. A year or two or (fingers crossed) three later, said doll gets torn apart. The cycle continues.

There was a switch this season, though: the bloodletting happened during the season, as a record eight coaches met the iron maiden between opening night and Valentine's Day. Is there anyone left to execute at season's end?

Well ... yes. Of course there is. After the jump, we tell you whom and guess their replacements.
