Oregon coach Mark Helfrich and Stanford's David Shaw shared some laughs when they met for the first time this offseason during an annual Pac-12 Conference meeting.

Although they had never talked before, the circumstances that brought them together made them feel like they had known each other for years. Both had been promoted from offensive coordinator to replace popular predecessors, Chip Kelly and Jim Harbaugh, after each moved on to NFL jobs.

Helfrich has No. 2 Oregon (8-0, 5-0) undefeated heading into Thursday night's matchup at sixth-ranked Stanford (7-1, 5-1) in what has once again shaped up as the Pac-12's game of the year. Shaw is 30-5 since taking over for Harbaugh in 2011, including leading the Cardinal to the program's first Rose Bowl victory in 41 years last season.
