The most obvious was Purdue's new anthracite gray alternate, paired with a patriotic white alternate lid in honor of Military Appreciation Day.

The most talked-about new designs were Iowa and Michigan helmet decals. The former replaced the Tigerhawk logo on the left side of its helmet with a No. 9 to remember former Iowa star Tyler Sash, who passed away earlier this week, and the latter brought back the helmet stickers it wore during first-year head coach Jim Harbaugh's playing days.
