They are the 6th Big Ten ranked in the top 25 including other undefeated teams Ohio St (2), Michigan (17) and Michigan St (16) with 1 loss Iowa (15) and Wisconsin (19). If you want you can include next year's new member Nebraska (6) and there would be 7 out of 12 members ranked in the Top 25.
The other five teams are all ranked in the Top 25 of the AP Poll.
The Wildcats will look to extend their winning streak to 6-0 to start the season for the first time since 1962 against Purdue this weekend. However after this weekend the road gets much tougher.
After the Boilmakers they will face off against Michigan St at home before heading away for two games taking on Indiana and Penn St and then returning home to face off against Iowa. They will close out their home schedule with a game against the Fighting Illini at Wrigley field before closing out the season against the Badgers in Madison. Luckily for the Cats they do not face Ohio St or Michigan this season.
