There was a perception of Matt Leinart during his time in Arizona that he didn't really care about being great, that he was somewhat lazy and unmotivated.
Released by the team just before the 2010 season, Leinart signed with the Houston Texans -- and re-signed with them in the offseason -- and is now set to start for the team in place of the injured Matt Schaub.
As a guest on the Sirius XM Blitz, the 28-year-old admitted he had some things to learn before he could be successful.
"I was young and I didn't know how to prepare," he said. "I've always worked hard...I just maybe haven't shown it in all different ways."
Leinart said getting injured in 2007 forced him to to learn what he had to do to be a good player in the NFL, and backing up a certain future Hall of Famer wasn't a bad thing, either.
"I was very fortunate to learn from Kurt [Warner], to play behind him and learn from him," he said.
Cardinals fans never really got a chance to see what Leinart learned in his time with the team, but everyone will have a chance to finally see what the former Heisman Trophy winner can do.
