Yes, only 2/6 seasons could even be moderately compared to the last 3, do you know how math works? Even then they weren't close. The best you ever did was 10 wins, and that only happened in half the first 6 years, then you jumped to 12, 13, and 15 wins out of nowhere once Stallions started cheating. Harbaugh was a better coach than Hoke, congrats I guess?
You're also very casually saying "the only difference was beating Ohio State" when you consider four of Harbaugh's first five games vs OSU were double digit losses by an average of 23 points. The only time he was close was with Hoke's recruits before he started cheating.
