The fans that cared then are the few that still show up to the games. Miller hasn't played at Utah in 27 years. He was a solid NBA guy, but not one that people got excited about. Most of your football crazy Utah fans don't even know who Miller/Van Horn/Doleac or Mottela even are. The Urban era that really started Utah as a football interest here local happened after these guys had their moment and not sure even Andre Miller can do much.
That being said, at least he's coached even if he wasn't good so it's a low risk prop
