I live in OKC. Can't remember if I read it or heard it on the radio, but Lincoln Riley stated the woodgrain alts are history. New alts in the future.
OU has had that same helmet logo for 50 (?) years or so. I assume they put the updated logo on the helmet for the Spring Game to see if the fans would accept it. I thought there would be an uproar, but it barely made the news. I noticed it immediately on TV, but those at the game couldn't tell the difference.
I'm not sure when the Jordan brand unis will be revealed, but I can tell you the fanbase would be set if the jerseys don't have "Sooners" across the chest. That's kind of an Oklahoma and Texas-area jersey tradition down here. Oklahoma, Oklahoma St (not anymore), Texas, Texas Tech, Arkansas (not anymore), SMU, etc all have or had large word marking above the numbers on the chest.
