Bo knows hoops. As a member of the exclusive 500-win club, University of Wisconsin head coach Bo Ryan has the second highest winning percentage among active coaches (with at least 500 victories) in college basketball, second only to North Carolina's Roy Williams. Ryan's formula for success can be traced back to UW-Platteville, where he won four national championships during a memorable 15-year run punctuated by two undefeated seasons. But there was still another hill to climb for Ryan, the all-time winningest coach in Division III history. After a short layover at UW-Milwaukee, where he coached the Panthers to their first back-to-back winning seasons in eight years, Ryan welcomed the challenge of proving himself all over again at the Big Ten level. And it didn't take long for Ryan to make his mark with the University of Wisconsin basketball program. In his first season, he guided the Badgers to their first share of the conference title in 55 years. Since then, Ryan has raised the bar to unprecedented heights, leading the Badgers to the four winningest seasons in school history.
