Swin Cash is all-in on the WNBA coming back to Detroit ... telling TMZ Sports the city and its fans deserve it -- no matter what the haters say!!
We spoke with the three-time champion at the Taylor vs. Serrano fight on Friday ... and asked her about the W's announcement that Motor City -- where Cash played from 2002 to 2007 -- would be home to a pro women's hoops team once again in 2029.
Of course, the Shock relocated to Tulsa in 2009 .
