Let's see here....2005....OU also lost 4 other games that year. Went to the Holiday Bowl to play Oregon. Oregon was a team that many thought should have had a BCS bowl bid since USC made the BCS title game.
What did OU do to them? As a 8-4 team, they beat Oregon.
Overall, 2005 was by far the worst team under Stoops.
BTW, TCU went on to be 12-1 that year.
Did you know Stoops also lost to unranked OSU in 2001 in Norman?
In fact, OU has doubled Stoops loss total at home the last 10 games, or better yet, the last 5 home games. Losing to 5ech and KSU. Beating ISU, A&M and FAMU.
