WNBA announces rules change to draft lottery format

Interesting change to the WNBA draft lottery rules announced just a bit ago:

Under the new format (which begins with the lottery following the 2015 season), the drawing will still be held among the four teams that did not make the playoffs (the “Lottery Teams”) in the immediately preceding season. Instead of assigning the odds based solely on the records of the teams in the immediately preceding season, the odds will be based on the cumulative records of the Lottery Teams over the two most recent regular seasons…..

The new format will also guarantee that the Lottery Team with the worst two-year cumulative record will end up with at least the third pick. Under the previous format, the Lottery Team with the worst single-season record was guaranteed to pick no worse than fourth.

I wonder how long the league had been thinking about this.
