Cardinals quarterback Matt Leinart is trying not to get caught up in that. He breaks down plays with coaches and teammates, but he said he doesn't live in fear that an errant pass, a wrong read or a bad pass drop (when the quarterback drops back to pass) will prompt coaches to give the starting job to Kurt Warner.
A player can't function like that, Leinart said.
