Just about every Saturday, it's safe to assume at least one Big Ten team will debut some kind of new uniform design.

In Week 3, four Big Ten teams unveiled a new design, three of which consisted of a new helmet wrinkle.

Indiana and Northwestern both introduced a new alternate lid to already extensive collections, while Iowa added a "TS" decal in memory of former safety Tyler Sash. In Week 2, the Hawkeyes replaced the Tigerhawk on the left side of their helmet with the No. 9, Sash's number at Iowa.

Michigan State debuted a new uniform for the second consecutive week, this time donning an alternate home jersey that featured sleeve accents.
