ESPN’s Bill Connelly ranked all 16 remaining undefeated teams earlier this week, and the Tigers came in at No. 5.

Clemson trails Ohio State, Alabama, Georgia and Michigan in Connelly’s rankings. Ohio State, Alabama and Georgia have largely been the consensus top 3 all season.

But Wolverines still being ahead of Clemson is a curious choice. Michigan’s résumé includes wins over Colorado State, Hawaii and UConn. In Big Ten play, Michigan has picked up unimpressive wins over Maryland and Iowa.

Meanwhile, Clemson now has a pair of ranked wins over Wake Forest and NC State. Despite that, Connelly has reason to doubt the Tigers moving forward.

Here’s Connelly’s analysis:

“The Tigers are in an interesting place at the moment. Their defense struggled against both Louisiana Tech and Wake Forest but came together last week; their offense has battled inconsistency but is now up to 16th in points per drive thanks in part to good field position and great red zone production. My SP+ ratings don’t trust them because they aren’t really dominating a weak ACC landscape, but their odds of running the table are obviously increasing by the day.”

Clemson will have more opportunities to prove itself in the coming weeks. Its road matchup at Florida State in Week 7 could be another top 25 showdown.

The Tigers are also set to face a potentially-undefeated Syracuse team on Oct. 22 and a tough Notre Dame squad in South Bend on Oct. 29.

This week, Clemson will make the trip to Boston College. Kickoff is at 7:30 p.m. ET on ABC.
