I think Harrell would be a slam dunk hire. Continues the Air Raid, but modernizes it a bit. Has connections out west with his time at Wazzu and USC. Played professional football. Was probably the most successful coach under Leach. Can bring some solid USC coaches with him that have less job certaintly under Helton. Hire him for 3.25 million and then you can afford a really solid DC for 1 million and still have a big chunk of cash for the rest of his staff. He would be option 1.
