Looking back on it now:
1990: We went 9-3, finished 3rd in the Big 8. Ranked #3 in the nation, we lost by 15 to #9 Colorado, 27-12. We then lost to unranked Oklahoma as the 10th ranked team, 45-10. We went to the Orange Bowl where we lost to #2 Georgia Tech as the #19 team, 45-21.
1991: As the 9th ranked team in the nation, we lost to #4 Washington by 15 points, 36-21. We tied 15th ranked Colorado and then lost to #1 Miami in the Orange Bowl, losing 22-0. We also tied for 1st in the Big 8.
1992: We lost as the 12th ranked team to #2 Washington by 15 points, 29-14. We then lost to unranked Iowa State as the 7th ranked team in the nation, 19-10. We won the Big 8 and then lost in the Orange Bowl to Florida State, the #3 ranked team, 27-14.
So...a couple of losses to unranked teams. And a loss to the top ranked team, two losses to the #2 ranked team, a loss to the #3 ranked team, and a loss to the #4 ranked team. That's a team not being able to win the big game. That's vastly different than Bo. But again, this is well into Osborne's career, so it's not exactly a fair comparison.
