In the world of rodeo, competitors are permitted to ride and rope on the amateur collegiate level and on the pro circuits at the same time.Unlike the NCAA, which rules athletes cannot compete in a collegiate and pro sport during the same season, the National Intercollegiate Rodeo Association and the Professional Rodeo Cowboys Association allow dual membership.And it’s been that way for many years. For example, Stephenville’s Ty Murray won both the NIRA and PRCA all-around titles while competing for Odessa College in 1989.One cowboy who is currently thriving on both circuits is Tarleton State roper Billy Bob Brown. Last weekend, Brown clinched the men’s all-around title in the NIRA’s Southwest Region, a super conference in the college rodeo ranks. At the March 28-30 ABC Rodeo in Lubbock, Brown lassoed the tie-down roping title with a blistering time of 7.8 seconds.Brown is a Tarleton junior agriculture business student. Though he has entered PRCA shows since he was 18, he said he will graduate from Tarleton before attempting to earn a livelihood as a rodeo cowboy.“I want a college diploma on my résumé — I want to have something to fall back on,” Brown said.Brown also helped Tarleton clinch the NIRA Southwest Region men’s team title at TSU’s 48th annual rodeo Stephenville. Tarleton’s women’s team also finished first in the region and TSU’s Katelyn Anthony won the women’s all-around title.Last weekend’s Tarleton Rodeo was the last of 10 regional regular-season shows for 2012-2013. From there, the region’s top teams and riders will advance to the NIRA’s College National Finals Rodeo held June 9-15 in Casper, Wyo.PBR updateJoao Ricardo Vieira, a rookie from Brazil, won the Professional Bull Riders’ tour stop last weekend in Des Moines, Iowa, and earned $47,115.
