It would be reasonable to assume Andrew Luck will be pulling for the San Francisco 49ers to win Super Bowl XLVII when they meet the Baltimore Ravens on Sunday.

Why not? The Indianapolis Colts quarterback's former coach, Jim Harbaugh, is now boss of the 49ers.

The truth is, Luck has lent more than his emotional support. He helped Harbaugh connect with Colin Kaepernick, the spectacularly talented young game-breaker who will be under center for the 49ers on Sunday.

Harbaugh was the Stanford coach when Luck played quarterback for the Cardinal in 2009 and 2010. Luck attended the Manning Passing Academy as a counselor in 2010, and there befriended a long, tall and somewhat obscure University of Nevada quarterback, Kaepernick.

Upon Luck's return to Stanford, Harbaugh asked if he had come upon anyone interesting. Luck doesn't recall the exchange precisely, but he knows what he thought of Kaepernick.

"I've obviously really enjoyed hanging around Colin, as a guy," Luck said. "Watching him throw, he's got an incredibly live arm. Obviously, he's incredibly athletic, as everybody can see. I've always had very high things to say about him."
