5. Iowa (4-1)
Last week: 4. The Hawkeyes had an opportunity to reveal themselves as contenders against Michigan. Instead, they were manhandled by a Michigan defense that conceded one rushing yard, forced four turnovers and sacked Nate Stanley eight times. Iowa left Ann Arbor battered, bruised and hoping the defeat is an isolated event and not a prologue to a bad stretch of football.
Next up: vs. Penn State, 7:30 p.m. Saturday, ABC.
