Iowa coach Fran McCaffery says the Hawkeyes need to find consistency on the defensive end.
After a solid effort in a win over Purdue the defense took a step back in an overtime loss at Minnesota. The 10th ranked Hawkeyes host 19th ranked Northwestern Tuesday night.
At 3-0 in the Big Ten the Wildcats are considered a surprise and McCaffery says it is about experience.
The emergence of Northwestern makes the Big Ten even tougher.
Hawkeye junior Joe Wieskamp says the Wildcats are playing like a team with something to prove.
This is the first time these two teams have ever played when both are ranked in the top 25. Wildcat coach Chris Collins says experience has been the biggest factor in their start.
Northwestern was 3-17 in the league race last season.
