By DAVID THOMAS NORTH RICHLAND HILLS -- It's the off-season, but Texas Brahmas coach Dan Wildfong and assistant coach Ron Vogel are busily working on bringing another Central Hockey League championship to the Texas Brahmas.The Brahmas don't take the ice for their first game for three months, but the work that Wildfong and Vogel are doing right now could determine whether the Brahmas will lift the Ray Miron President's Cup for the second time in three seasons.They are recruiting players to fill the 2010-11 roster.This is mid-level professional hockey, not the NHL.
