Creighton has gone .500 or better in league play 22 of the past 23 seasons. Xavier has been .500 or better for 36 consecutive years, the longest active streak in the country. Through multiple leagues and multiple coaches, Creighton and Xavier have been consistent winners for nearly — or more than, in Xavier’s case — a quarter of a century. Both teams are in serious jeopardy of enduring losing conference records this year, though. The Bluejays are 3-5 after losing five of the last seven games. The Musketeers are 3-6 after losing four straight and six of their last eight.
