Absolutely, no asterisk.
In a sense, the entire season has an asterisk for everything, not just team sports, because of all the craziness. But that will not diminish one iota what this team has done--even if they win out, gain the Big 12 titles (regular season & tournament), and then win the national championship. That's a huge if, by the way. But if they do win those titles, they will have earned it on the court--where it should be earned.
