Based on multiple reports, Kelly was seriously considering Joe Moorehead. Don't know that he interviewed, but they at least did a lot of background research on the guy. Moorehead was great at Penn St 3 years ago, but you never hear how bad his offenses were at Miss St where they had the worst offense in the SEC. A great offensive mind should never have an offense as bad as Miss State had this year. Coaches eventually get figured out by other coaches. There were times when BVG and Tenuta were very good DCs (BVG was considered the best in the country when at UGA); however, by the time both got to ND they were washed up. Opposing coaches had figured them out.
I don't know that Tommy will be successful or not, but I do think he and Taylor will bring new ideas to the offense, just like Clark Lea did to the defense.
