I feel for you OSU fans, having to return home after another embarrassing loss in front of a national audience. But is the result really a surprise, or were you just engaging in wishful thinking? One only had to compare the respective schedules.
In the regular season OSU played a total of 3 ranked teams (Perdue, PSU and UM), none of which was ranked higher than 23rd at the time. LSU played 7 ranked teams (Va Tech, S. Carolina, Florida, Kentucky, Auburn, Alabama, Tennessee), none of which was ranked lower than 18th at the time. Simply put, the Tigers appear to have been better battle-tested long before they reached New Orleans, whereas the Buckeyes cruised through the B10 for the second year.
If you disagree, just look at the final rankings. LSU beat 5 of the top 15 teams. OSU beat nobody among that group (UM finished at 18).
