Tommy Grady, who quarterbacked the Oklahoma City Yard Dawgz parts of the last two Arena Football League seasons, signed Wednesday with the Utah Blaze. Grady threw for 4,307 yards and 81 touchdowns this season for Oklahoma City. Grady, a former Oklahoma player who transferred to the University of Utah, is the Blaze’s first signing of the free agency period. He leaves a Yard Dawgz franchise that finished 6-10 last season — and has been rumored as leaving Oklahoma City. Yard Dawgz coach Sparky McEwen said he has not heard anything about the team moving. “There’s a lot of rumors out there,” he said Wednesday night. Steven Sylke, head of ticket operations, said he thinks there isn’t any merit to talk the Yard Dawgz will leave Oklahoma City. “I think people are just spitting out places where they’d like a team to go,” Sylke said. Owner Phil Miller and general manager Christie Cook could not be reached for comment. The Yard Dawgz have called Oklahoma City home since 2004, spending five seasons in the now-defunct af2 and were a member of the reorganized Arena Football League in 2010. San Jose, New Orleans, Kansas City, Philadelphia and Pittsburgh will join the AFL for the 2011 season, which begins in March.
