Notice I said "Should Be". That does not necessarily mean that they will be.
1. Clay Helton, USC. It is real simple. Either Helton has a successful season or both he and AD Swan are gone. With a schedule that features games at Washington and Notre Dame, plus home games against Stanford, Utah and Oregon, one may think that 8-4 would be a good record, but 9 wins should be the minimum to keep his job. USC has lost several potential solid recruits and had by their standards, a sub-par recruiting season (#18 Overall and #3 in the Pac 12). The alumni wanted Helton's head last season and will not sit still for anything less than a 9 win season, nor should they.
2. Chris Ash, Rutgers. Why is he still there. Last seasons team was expected to improve on a 4-8 season in 2017 but instead, went 1-11 and never scored more than 17 points in their last 11 games. This season sees a schedule that has Liberty and UMass visiting as well as a non-con game against Boston College. Crossover games include a trip to Illinois. It will take at least 4 wins to save his job, and that may not be doable.
3. Lovey Smith, Illinois. Why this man is still the Head Coach of Illinois is anyone's guess. Last year did show some improvement, but the fact remains that 4-8 is his best record in 3 years at Illinois. 3 of his 4 wins last season came against Kent State, Western Illinois, and Rutgers. The 2019 schedule has no Power 5 teams on it's non-con schedule and Rutgers at home. Will Illinois settle for another 4 win season? If so, why?
4. Chip Kelly, UCLA. Surprised? Shocked? We all know that there is no way UCLA will fire Kelly, but that does not mean that they should not get rid of him. Look at the facts. His team went 3-9 last season which included a win against USC, who also did terrible. Things are only getting worse for Kelly. He has lost several players who have left the team for various reasons. He had a terrible recruiting class which ended up 43rd nationally and between 7th and 9th in the Pac 12. This season's schedule includes games at Cincinnati, Washington State, Arizona, Stanford, Utah and USC, plus home games against San Diego State and Oklahoma. 6 wins seems to be a daunting task, but another 3 win season is unacceptable. Something is wrong at UCLA.
5. Jim Harbaugh, Michigan. How long is Michigan going to settle for being 2nd best in the Big 10? or 3rd best? or 4th best? Harbaugh ended what would have been a highly successful season by being destroyed by Ohio State and hammered by Florida in their Bowl Game. In 4 years at Michigan, Harbaugh has never lost less than 3 games. Habaugh is a good HC, but he has always been unable to win the big game in his college career. He has never one a conference championship in college ball. This year is his best chance. He gets Notre Dame, Michigan State, and Ohio State at home. IF he cannot do it this season, it is time to move on.
