The white helmets are no surprise given Pollard's background at Maryland & Wisconsin.
The current question revolves around what type of decal to put on the helmet. Specifically do you try to identify with the school name or the team name/mascot? The NFL teams almost all go with the team name/mascot. The Browns have nothing; the Bears, Packers, and Giants have city initials; the Chiefs have a hi-bred. The other 27 teams all feature their team name/mascot on the helmet.
College teams seem to be more evenly split between decal styles. The Big XII and the Big Ten both have a majority of the schools that feature the school initials, but there are still prominent examples of mascots on the helmets.
An interesting difference is that fans of a particular team tend to identify more with the team name - i.e. we are "Cyclones". From the outside, teams are identified more by the school - i.e. we play against Kansas or Colorado rather than the Jayhawks or the Buffalos. If you want to build more national identity, it probably makes more sense to go with either I-State or ISU rather than Cyclones.
