The Trojans have been dominant for pretty much the entirety of Carroll’s tenure, but they may have reached their peak between 2003 and 2005, when, for a period of nearly two years, they held the No. 1 spot in the Associated Press Top 25. Their 33 weeks atop the AP poll is the longest streak in college football history—by a wide margin.
