Andrew Luck played for Jim Harbaugh at Stanford his first two years of college. So surely the No. 1 pick of the 2012 NFL draft by the Indianapolis Colts must have some perspective on Harbaugh in light of reports that current San Francisco 49ers' players do not want to play for him.

Luck, a two-time Heisman Trophy runner-up for the Cardinal, was asked about his old college coach in a conference call with writers who cover the Houston Texans on Wednesday.

“I don’t know, I really don’t,” Luck told the Texans writers as they prepare for the game between Houston and the Colts.

“It seems to sort of be the nature of sports media now to love on the story with conflict within an organization. Players and coaches. I take everything with a grain of salt. I’m not in their locker room. I don’t know what’s going on, if anything’s going on.”

But what about Luck’s own relationship with Harbaugh?

“I know my experience with coach Harbaugh was great,” Luck said. “We won a lot of games, practiced hard, played hard. Learned a lot about football and life with him.

“I feel very fortunate that I was coached by him in college.”
