Interesting indeed. I hadn't heard that story either.
Here are a few things about Helfrich in support of what I have been telling people about his role in Kelly's offense:
Initially, after the 2006 season
Mike Bellotti contacted Helfrich about possibly joining Oregon before
Chip Kelly was hired in 2007, but Helfrich declined to leave
Colorado after only one season.[SUP]
[9][/SUP] Two years later, Helfrich was named Oregon's offensive coordinator and quarterbacks coach on April 30, 2009, replacing Chip Kelly's position as he had been promoted to head coach.[SUP]

During Helfrich's four seasons as Oregon's offensive coordinator the offense produced tremendous success, ranked highly nationally in several offensive categories and became well known for their extremely fast-paced offense built around speed. Although Chip Kelly called the plays on offense, Helfrich still played an integral role in Oregon's system.[SUP]
[10][/SUP] He had a large amount of involvement in the game planning, scripting, and coaching on a weekly basis while having a high amount of input in what plays are called and why they are called.[SUP]

With Helfrich coordinating under the philosophy of innovative spread offense guru Chip Kelly, the Ducks played in four straight BCS bowls from 2009 to 2012, won three straight Pac-12 Conference championships,[SUP]
[12][/SUP] and continuously energized college football with one of the nation's best offenses in scoring, rushing, and total offense in each of those four seasons. As offensive coordinator during the Kelly era, the offense averaged 44.7 points per game with an average of 283.4 rushing yards and an average of 500.7 yards of total offense. In 2012 Oregon's offense was hailed as its best ever[SUP]
[13][/SUP] as they averaged 49.6 points per game with an average of 537.4 yards of total offense with 315.2 of those yards per game from rushing.
