Native Houstonians are rare on the sports radio dial. Most of the guys on 610 and 740 came to Houston as adults, and don't identify with Houston teams as strongly as people who grew up here. Sports Rap host Ralph Cooper is a notable exception to that rule. He's not an uncritical homer or anything like that, just a guy with a knowledge of Houston sports that's as broad as it is deep. The Worthing graduate got his start in the sports world in the early '70s and has been at every major Houston sporting event since, including the 1974 Super Bowl at Rice Stadium, the Phi Slamma Jamma and Luv Ya Blue eras, and the pair of Muhammad Ali bouts at the Dome in 1971. Cooper covers everything from junior high football to women's pro basketball, all from a Houstonian and African-American perspective. What's more, he does it with wit, punch and style. If you want to be in the know, hangin' with Mr. Cooper every weekday from 5 to 7 p.m. is the thing to do.
