Patterson has one shared title in 9 years. Gundy has 1 outright in 10 years. OSU has finished above TCU in the conference 6 out of 9 times. OSU has finished 2nd 3 times, TCU once.
Don't know how you exactly quantify good losses, bad losses, good wins and bad wins. One way is the quality of the roster. TCU consistently has a better star-rated roster. If that is in any way meaningful, there's only one way to cut it. OSU has more conference wins in the last year, last 2 years, last 3 years, last 4 years, last 5 yrs, last 6 years, last 8 years and last 9 years. The only span of time OSU hasn't had more wins is the last 7 years when the win total were exactly the same.
