After months stuck in mediocrity, the Big 12 is starting to show a glimmer of promise as the NCAA tournament approaches.

Kansas State and Oklahoma State surged to finish the regular season, providing the conference a trio of teams that could be poised to make a deep postseason run. It's a positive development for a league that spent most of the season struggling to claim a place in the national dialogue.

Even with three teams now ranked in the top 15, the lasting image from Big 12 play may be perennial national powerhouse Kansas losing at lowly TCU.

There's still time to change that, if the Big 12's top teams can play up to their potential and avoid more confounding upset losses in the postseason.
