Seems a safe bet that this is one of the most competitive categories in this whole damn book. In this corner, you have Eric Nadel, iconic voice of the Texas Rangers for more than 30 years. In this corner, you have Ralph Strangis and Darryl Reaugh, the only hockey announcers North Texas has ever known. Yet standing in the middle, stiff-arming the competition, stands Brad Sham, Dallas' version of Vin Scully. Yes, he roots for the Cowboys. But he does it eloquently, almost subtly, somehow without being a homer. And he's by no means a shill for Jerry Jones, evidenced by his memorable, disgusted calls of a drop by Roy Williams and a missed block leading to Tony Romo's injury by rookie fullback Chris Gronkowski. Quipped Sham before a win over the Texans last year, "If the Cowboys can keep from slipping in their own drool they'll be OK." Touche.
