Winning the conference tourney still gets you a trophy and the title. Getting a regular season title is cool, but a conference tournament title is even bigger, IMO, because it generally means you're playing your best ball going into post season.
Plus, no one will be talking about some school that won the regular season of the Big. They'll be talking about the Huskers shocking everyone going projected last to winning the tourney.
I see that Brent Musburger signed a contract with the sec network and will no longer announce football games on ABC or ESPN. Thank god we don't have to listen to him anymore.
