Top stats to know: Bo Ryan's best numbers

Wisconsin men's basketball head coach Bo Ryan abruptly announced his retirement Tuesday night. With that in mind, we offer up 10 stats to pay tribute to his statistical history.

• Ryan became head coach of the Wisconsin-Platteville men's basketball team in 1984-85. The team went 9-17. Ryan has coached every season since then with other stops at Wisconsin-Milwaukee and Wisconsin. He never had a losing season again.

• Ryan's greatest success was with UW-Platteville, for which he won four national championships between 1984 and 1999 (matching the most for any Division III school). There have been three unbeaten seasons in Division III men's basketball. Ryan was the head coach for two of them (1994-95 and 1997-98).

• Ryan also had amazing success at Wisconsin, where he became head coach in 2001. The Badgers have the 11th-most wins of any Division I program since he became head coach.

• Ryan is the school's all-time winningest coach with 364 victories and his 14 NCAA tournament appearances are the most in program history. No other Wisconsin head coach made more than three trips to the tournament and only one (Bud Foster) is within 100 wins of Ryan's victory total.

• Including his time at UW-Platteville, Ryan finishes his career with a 747-233 overall record. The 747 wins rank 25th in NCAA history (all divisions).

• The Badgers made seven NCAA tournament appearances before Ryan became head coach. He tripled Wisconsin's total to 21 with the 14 the team made with him as head coach.

• Wisconsin had the best record of any team in the Big Ten in Ryan's tenure (among teams in the league more than two seasons), edging out Ohio State.

• Ryan's teams have always prided themselves on defense. His 1996-97 UW-Platteville team allowed a Division III-record low 47.5 points. The Badgers ranked No. 1 in Division I in scoring defense twice in the last nine seasons and ranked in the top 12 in eight of the last nine.

• Since Ryan took over as head coach, the Badgers have given up 59 points per game, the lowest opponents' scoring average in Division I.

• Ryan can say he basically went out on top with how the Badgers fared last season. His 36 wins, .900 win percentage and No. 3 final AP ranking are all the best he had at Wisconsin, along with Wisconsin's first national championship game appearance since 1941.
