I came across a listing of the top 20 basketball coaches all-time in terms of NCAA Division 1 wins.
Here is the list in order, followed by their win total and winning % in NCAA tournament games-
Mike Kryzewski- 38 seasons. 971 wins. 82 tourney wins (most all-time), 77% winning percentage (2nd behind Coach)
Jim Boeheim- 37 seasons. 938 wins. 52 tourney wins, 64% winning percentage
Bob Knight- 42 seasons. 902 wins. 45 tourney wins, 64% winning percentage (averages a little over 1 win per season coached).
Dean Smith- 36 seasons. 879 wins. 65 tourney wins, 71% winning percentage
Adolph Rupp- 41 seasons. 876 wins. 30 tourney wins, 63% winning percentage
Jim Calhoun- 40 seasons. 873 wins. 51 tourney wins, 72% winning percentage
Jim Phelan- 49 seasons. 830 wins (somewhat misleading- a lot of these were in Division II)
Eddie Sutton- 37 seasons. 804 wins. 39 tourney wins, 60% winning percentage
Lefty Driesell- 41 seasons. 786 wins. 16 tourney wins, 53% winning percentage
Lute Olson- 34 seasons. 780 wins. 46 tourney wins, 62% winning percentage
Lou Henson- 42 seasons. 779 wins. 19 tourney wins, 48% winning percentage
Hank Iba- 41 seasons. 764 wins. 15 tourney wins, 68% winning percentage
Ed Diddle- 43 seasons. 759 wins. 3 tourney wins, 43% winning percentage
Phog Allen- 37 seasons. 746 wins. 10 tourney wins (coached many seasons before NCAA tourney started)
John Chaney- 34 seasons. 741 wins. 23 tourney wins, 58% winning percentage
Jerry Tarkanian- 31 seasons. 729 wins. 38 tourney wins, 68% winning percentage
Norm Stewart- 38 seasons. 728 wins. 12 tourney wins, 43% winning percentage
Ray Meyer- 40 seasons. 724 wins. 14 tourney wins, 47% winning percentage
Don Haskins- 38 seasons. 719 wins. 14 tourney wins, 52% winning percentage
Roy Williams- 25 seasons. 710 wins. 62 tourney wins, 75% winning percentage
Here is TIARA by comparison- 18+ seasons. 400 wins. 5 tourney wins, 42% winning percentage.
Here are the top 5 in tourney wins-
Mike Kryzewski- 82 wins, 38 seasons, 2.2 wins per season coached. also #1 in total wins, including regular season
Dean Smith- 65 wins, 36 seasons, 1.8 wins per season coached. #4 in total wins
Roy Williams- 62 wins, 25 seasons, 2.5 wins per season coached. #20 in total wins
Jim Boeheim- 52 wins, 37 seasons, 1.4 wins per season coached. #2 in total wins
Jim Calhoun- 51 wins, 40 seasons, 1.3 wins per season coached. #6 in total wins.
Clearly, it is easier to rack up more total wins if your coaching career includes more seasons with the 64 team field.
But again, for comparison, here is TIARA- 5 wins, 18 seasons, 0.3 wins per season coached.
Here are the top 5 in tourney win %-
Coach- 47 wins, 25 seasons, 1.9 wins per season coached, 83% winning percentage. not in the top 20 in total wins
Mike Kryzewkski- see above, 77% winning percentage
Larry Brown- 19 wins, 8 seasons, 2.4 wins per season coached, 76% winning percentage. not in the top 20 in total wins
Rick Pitino- 48 wins, 27 seasons, 1.8 wins per season coached, 75% winning percentage. not in the top 20 in total wins
Roy Williams- see above, 75% winning percentage
Again, for comparison, here is TIARA- 5 wins, 18 seasons, 0.3 wins per season coached, 42% winning percentage.
I am going to give Doughnut the benefit of the doubt here (always dangerous) and assume that he did look at least something objective in deciding to make the offer to TIARA. It is pretty clear that even for Doughnut, 5 wins in 18 seasons and a losing record would not be compelling.
So it had to be regular season wins. 400 wins sounds like a lot. But again, looking at the list of the top 20 all-time wins, we have a lot of names of coaches with impressive longevity, but not a lot of postseason success (Ray Meyers, Norm Stewart, Ed Diddle, John Chaney, etc).
Doughnut may have helped push TIARA along the path of longevity, by offering a contract with prohibitively expensive buyout terms. But he certainly did not push the program along the path of likely postseason success, based on TIARA's track record.
We want character. We want consistent deep runs in the postseason (not banners every year, but not a lot of skipped years and early outs). A banner from time to time would also be nice.
Based on his track record (including dealing with off the court issues at prior stops), we are going to get none of the above (character, deep runs, banners) from TIARA. If only Doughnut had done at least a little checking beyond total regular season wins.
