Most players re-signed with the league, but some didn't. The deadline for having contracts signed was Wednesday. If a player didn't meet that deadline, then they won't be in the league this season. Losing sponsors is never cause for celebration, but it doesn't have to be cause to fret either. You have to remember, the WNBA is a business, first and foremost.
Sponsors come on board because they're seeking very specific results and rewards.
If their objectives aren't met, it makes sense that they take their dollars elsewhere. It's not personal, it's business. And it doesn't mean that the league is on the brink of folding. Yes, the ABL contends that the NBA used its power to get television networks not to air ABL games, thereby contributing to their demise. It's no secret that the WNBA is backed by the NBA's phenomenal marketing muscle.
