Add me to the vocal majority that is adamantly against changing our beloved helmets, jerseys, or pants to anything other than they currently are!
Deep breath..... However, I am not necessarily against pulling out the white helmets once every two to three years for a little nostalgia. All of these helmet and uniform mockups are just for fun and nobody involved in the decision process would consider changing our uni to something resembling a Power Ranger or an Arena League team.
As for the helmets in the list: I could be conservative, but I'll say that the last one is the neatest design IF we ever did a off-the-wall alternate uniform. Take that dark chrome/gray houndstooth, Script A on one side and numbers on the other. One things for sure; they'd sell a ton of them as replica / mini helmets.
