PHOENIX — From the baseball diamond at Camelback Ranch, the Arizona Cardinals’ home rises like a silvery moon. The University of Phoenix Stadium was the site of one of Tim Tebow’s many football triumphs. After the 2006 season, he was a member of the Florida team that upset top-ranked Ohio State in the national championship game.
Tebow, a reserve quarterback, scored two touchdowns, one by air and the other with his legs. Nearly a decade later, Tebow, 29, who spent three seasons in the N.F.L., took a step Tuesday in his quest to earn respect on another team, in a different sport, when he made his debut in the Arizona Fall League.
