If you still think a gang of women on roller skates sounds precious and cute, you might be hanging out with Robin Thicke too much. In just five short years, the Nashville Rollergirls have graduated from rumbling in a fairgrounds outbuilding to packing out brawls in the venerable Municipal Auditorium with jaw-bruising style. The bouts may be civilized with rules, referees and protective gear, but our ladies of maximum discomfort have been socking it to the competition this year: Going into the home stretch, the varsity All Stars team is 7-and-3, and the junior varsity Brawl Stars are 4-and-2. In the final round of the regular season, they butt heads with Cincinnati’s Black Sheep and Violent Lambs. The All Stars’ slot in the WFTDA Division 1 Playoffs is already secure, but the Cincinnati teams aren’t pushovers — they, too, have impressive records, not to mention a few OG skaters who’ve been on the roster since their inaugural season in 2006.
