"They're all based out of the spread philosophy and that is what intrigues me the most," Whittingham said.
The 65-year-old Erickson will share coordinating duties with Brian Johnson, who served as offensive coordinator last year. However, Whittingham said Erickson will have the "last say."
Whittingham said Johnson wasn't viewing Erickson's hiring as a demotion and that the two had "a conversation" to discuss possible hiring scenarios.
"Brian knew all along we wanted someone who was the best fit for our offense and needs," Whittingham said. "This in no way, shape or form diminishes my opinion of Brian or what I think his coaching future is."
Whittingham said the coaching duties of the other offensive assistants remain the same, with Jay Hill over running backs, Johnson over the quarterbacks and passing game coordinator Aaron Roderick in charge of the receivers.
The Utes believe Erickson will be a valuable addition to their recruiting efforts as well, particularly for quarterbacks. Whittingham described him as a 'coast to coast' recruiter who could go into anyone's home.
