Here's my case for top five:
USC, which has been ranked No. 1 in a national-record 32 straight AP polls, also is riding an NCAA record 15-game winning streak over AP Top 25 teams.
Since 2002, USC is undefeated in regulation in its last 47 games, losing at Washington State, 30-27, in overtime in 2002 and at California, 34-31, in triple overtime in 2003. Their last loss in regulation was at Kansas State, 27-20, on Sept. 21, 2002. Think about that for a second. Had kicker Ryan Killeen connected on his field goals in both overtime losses, USC might be going into this weekend's game against UCLA looking to break Oklahoma's 47-game winning streak from 1953-57, which is the longest in NCAA history.
One of the reasons USC has been so successful during that stretch has been its high-scoring offense. The Trojans have scored at least 22 points in their last 48 games. During this stretch USC has scored 30 or more points 39 times, 40 or more 29 times, 50 or more 10 times and 60 or more three times, including their 70-17 rout of Arkansas this season.
yeah that's fine, but you got to admit that they have also played in a conference that hasn't really shown much defense in the past 3 or 4 years, outside of USC's of course.
Like I said, top 10...probably 6 or 7, but they aren't the best ever. They aren't even better than last year's incarnation.
