Saturday's Week 5 college football slate is stacked with ranked road tests. NCAA.com's latest AP Top 25 preview flagged three ranked-versus-ranked games: No. 5 Ohio State at No. 14 Iowa at 3:30 p.m. ET, No. 7 Alabama at No. 16 Mississippi State at noon, and No. 8 Florida at No. 25 Missouri at 3:30 p.m. No. 3 Notre Dame also visits North Carolina at noon in a notable nonconference spot.

Florida is the poll's biggest recent mover, jumping from No. 21 to No. 8 after beating Ole Miss. Mississippi State climbed into the teens after knocking off Missouri. Iowa entered the top 15 after a last-second win over Michigan. Those shifts set up Saturday's stakes: Ohio State tries to stay in the Copa chase on the road, Alabama tests an undefeated Bulldogs group, and Florida tries to keep its surge alive in Columbia.

Television windows will vary by conference package, but the noon-to-evening board gives casual fans a clear path: early SEC and Notre Dame, mid-afternoon Big Ten and Florida, then night games headlined by No. 4 Miami at Clemson at 7:30 p.m. ET.

Backstory: six ranked-versus-ranked games last week scrambled the poll; this week's three headliners can scramble it again before October deepens.
