I think refs at all levels have always made mistakes in the past. Instant replay has provided a method to try to correct the bad decisions. However, as the replay system has matured, officials have grown more reluctant to correct those bad calls. One wonders why. Are there so many they don't want to admit they have some many? Does it provide an avenue for the SEC and other conferences to sway the outcome so that the perceived better teams will make it to the playoffs? Are the Conferences so money happy that they want to make more money for them and their teams? Are the refs on the take or paid by the Conferences for them to play favorites? Deep down, I don't think so, but each week so many bad calls are made that inquiring minds wonder.
