Weekly college football top 25 rankings are a big part of every season, and Athlon Sports will update its top 25 following the games each weekend. The third weekend of the 2017 season was filled with exciting games and intriguing non-conference and league matchups. Alabama defeated Colorado State to remain No. 1 in the rankings, but Clemson closed the gap after knocking off Louisville in convincing fashion on Saturday night.
Oregon kicked off its first season under head coach Willie Taggart with a dominant blowout of FCS member Southern Utah, and then came out scorching hot against Nebraska before holding off a second-half rally to pull to 2-0.
