The Utah hook'em horns. A little less well known, but equally ripped off tradition. That's right, a long time and well known Texas tradition has made its way into the former Real Salt Lake stadium. Of course, since Utah starts with a U, the fans and team can steal any tradition that resembles a U. But it isn't really stealing if you keep your fingers more vertical or use more fingers than other schools right?

And as for the "changing to darker colors = stealing another teams' colors," Alabama, Oklahoma, Arkansas, Rutgers, and all the other teams that aren't pansy light red want their helmet back. You can keep the non-matching jerseys.
