No they weren't.

The week heading into the bowl, they were getting top 25 votes.
Not that it matters. They were the best team we could have played and we played the game in the best location we could have. I'm sure you, like the rest of us, had a GREAT time in Boca Raton. Wonderful weather, super team hotel and picturesque stadium overlooking the Atlantic Ocean. It was the best bowl trip I have had and many will agree with me.
If you didn't enjoy that trip then you don't enjoy bowl games
At no time were they ever close to being in the Top 25. The whole year with our record of 13-1, the highest we ever achieved is 18th.
Only reason they were 11-2 was against a lighter then air schedule:

The toughest team they played was Arkansas, and lost; not that ours was much better but, we didn't lose to directional Michigan in the process.
