More than one-fifth of last week’s Coaches Poll top 25 teams took an L during this past weekend’s college football action, ensuring that we’ll see some prominent changes in the updated rankings as we look ahead to the Week 5 games as the coaches fill out their ballots.

Stat to know: Luke Altmyer is the third Big Ten QB with 10 passing touchdowns and no interceptions through a team's first four games of the season since 2004. He joins Justin Fields (Ohio State) in 2019 and Kyle Orton (Purdue) in 2004.

It seemed the college football world moved past Clemson after the opening 34-3 loss to Georgia, but reports of the Tigers’ demise may have been greatly exaggerated. Since that loss, Clemson has a 66-20 win against Appalachian State and a 59-35 win against NC State on Saturday.
