Brooks - Did okay with little talent and slowly improved the program. His stamp on the program was about Oregon being a family atmosphere, and that still carries through today.
Bellotti - Did a lot with little talent. Slowly improved the program. Got robbed of a shot at a national title. Him stepping aside for Chip was huge, and Oregon owes him for that.
Kelly - Came in with a new scheme that other teams were not ready for. Did a lot with slightly better talent than Bellotti. He wasn't a great recruiter, but his new scheme did attract some good players and he was great at putting them in positions/schemes to succeed. Changed the trajectory of Oregon in a huge way. Much love for him.
Helfrich - Good person, good OC and QB coach, but not a good head coach, game coach, or recruiter. Marcus was his gift to the program.
Taggart - All talk, but a horrible coach. I do think he changed how we recruit and hired assistants who could recruit well.
Cristobal - Good HC and recruiter, but a horrible game coach. Herbert would have been so much better with a better coach and scheme. He did win some big games, and elevated our program. He also lost some big leads and was almost always out-coached, and relied on talent.
Lanning - Great HC and recruiter, but needs some work as a game coach. I often compare him to DeBoer. DeBoer is a great HC, and game coach, but not a great recruiter. It's hard to find a coach that embodies both of them. If they were co-head coaches for a team, they would shred. Ewww, can't believe I said that.
Knight - While not a coach, I felt he deserved to be on the list for obvious reasons.
All these coaches did something for this program and are the reason the Ducks are a top football program, which is crazy considering Eugene is a small town on the West Coast in a conference plagued by poor leadership over the years.
