The 2015 college football season only has a few weeks left, during which time the playoff picture will clear up, and teams will either be preparing for a bowl game or having the offseason start earlier than hoped. So much can still happen between now and early December, and the results of the next few weeks will have a major impact on the rankings.
Not just the playoff ones and those that are part of media and coaches polls, but also the Bleacher Report power rankings.
Bleacher Report's power rankings are comprised of an average of five sources: B/R's weekly Top 25, the Associated Press Top 25, the Amway Coaches Poll, ratings guru Jeff Sagarin's computer rankings and the author's personal rankings for every FBS school.
