Nike has been generally terrible for us in uniform design, though somewhat mitigated things with last season's basketball uniform and throwback (however, the numbers on the throwback are too small).
Now that the B1G is intending to become a super conference, it's time for a classic football uniform with old gold helmet, trim, and pants that is readily-identifiable as Purdue, so as not to be confused with Vandy or Wake.
No problem with black helmets as part of an alternate uniform, but they should be the Hank Stram era lids with old gold stripes.
It is inconceivable to me that Nike could not produce a great set, unless they assigned some kid with a set of markers and comic books to design it.
