There are a lot of complicated ways to evaluate coaches. (If you want a more complicated measure, here is something I wrote about this back in the Fall.) But sometimes the simplest measure is the best measure. Who has the most NCAA titles? Who has the most wins? And using the Pomeroy Rankings we can break it down to an even simpler level. Who wins the most possessions? If you outscore your opponent on more trips down the floor, eventually good things will happen.

Today, I look at the coaches with the best per possession numbers over the last five years. If you’ve followed my writing for the last few years, you’ve seen this table frequently. But I thought it was time to update the table with the data from the 2011-12 season. I’ve also decided to focus on the last five years to allow some of the recent success stories to climb the list. (I include the 10-year table at the end for the curious.)

The following table shows the

AAO = Average Adjusted Offense

AAD = Average Adjusted Defense

AEM = Average Efficiency Margin (Offense – Defense)

Here are the coaches with the top efficiency margins over the last five years:

AEM Rank Coach AAO Rank AAD Rank Teams 33.0 1 Bill Self 119.2 2 86.1 1 Kansas 31.2 2 John Calipari 117.3 3 86.1 2 Kentucky, Memphis 30.4 3 Mike Krzyzewski 120.1 1 89.7 9 Duke 28.6 4 Thad Matta 116.7 5 88.1 5 Ohio St. 27.3 5 Bo Ryan 115.8 9 88.5 6 Wisconsin 27.0 6 Roy Williams 116.5 6 89.5 8 North Carolina 25.8 7 Jim Boeheim 116.5 7 90.6 15 Syracuse 24.7 8 Rick Barnes 115.4 11 90.6 14 Texas 24.4 9 Tom Izzo 114.3 15 89.9 11 Michigan St. 24.4 10 Bob Huggins 115.1 13 90.7 16 West Virginia 23.4 11 Rick Pitino 111.2 31 87.8 4 Louisville 23.1 12 Jim Calhoun 113.9 16 90.9 19 Connecticut 23.0 13 John Thompson III 113.8 17 90.8 17 Georgetown 22.6 14 Jamie Dixon 116.5 8 93.9 41 Pittsburgh 22.5 15 Matt Painter 111.4 30 88.9 7 Purdue 22.1 16 Frank Martin 112.9 19 90.8 18 Kansas St. 21.6 17 Dave Rose 113.0 18 91.4 20 BYU 21.2 18 Billy Donovan 116.9 4 95.6 56 Florida 20.6 19 Mark Few 112.9 20 92.3 23 Gonzaga 20.5 20 Scott Drew 115.3 12 94.7 49 Baylor 19.8 21 Frank Haith 114.7 14 94.9 52 Missouri, Miami (FL) 19.4 22 Mike Brey 115.7 10 96.2 58 Notre Dame 19.4 23 Mike Anderson 111.9 27 92.6 26 Arkansas, Missouri 19.3 24 Ben Howland 112.7 22 93.4 35 UCLA 19.2 25 Jay Wright 112.8 21 93.6 36 Villanova 18.8 26 Lorenzo Romar 112.0 25 93.1 28 Washington 18.4 27 Sean Miller 111.7 29 93.2 30 Arizona, Xavier 18.3 28 Bruce Weber 108.4 47 90.0 12 Illinois 18.1 29 Steve Alford 111.9 26 93.9 40 New Mexico 18.0 30 Leonard Hamilton 105.6 75 87.6 3 Florida St. 17.2 31 Randy Bennett 112.7 23 95.5 54 St. Mary's 17.0 32 Kevin Stallings 112.2 24 95.2 53 Vanderbilt 17.0 33 Tony Bennett 106.8 65 89.8 10 Virginia, Washington St. 16.9 34 Seth Greenberg 108.5 44 91.6 21 Virginia Tech 16.7 35 Steve Fisher 108.4 45 91.7 22 San Diego St. 16.6 36 Fran Dunphy 109.9 35 93.3 31 Temple 16.5 37 Brad Stevens 109.0 40 92.5 25 Butler 16.3 38 Mark Turgeon 110.4 34 94.2 45 Maryland, Texas A&M 16.3 39 Tubby Smith 109.4 38 93.1 29 Minnesota 15.6 40 Anthony Grant 106.0 72 90.4 13 Alabama, VCU

For the first time since I’ve been tracking these stats, Bill Self has taken over the top spot in the coach rankings. And this season might be Self’s finest performance. Thomas Robinson has always been an explosive player. But Self has groomed him from an inconsistent freshman into the national player-of-the-year favorite. Tyshawn Taylor’s emergence as a polished player is equally remarkable. But it is Self’s consistent commitment to defense that has allowed his team to win conference titles year after year.

Bo Ryan remains a bit of an enigma on this list due to a lack of postseason success, but other coaches have posted great regular season numbers without post-season success too. Rick Barnes teams are frequently viewed as NCAA tournament disappointments. And John Thompson III is an even more extreme example. This table includes data from 2007-08 to 2011-12, and JT3 is the 13th best coach in that span. But John Thompson III has one NCAA tournament win in that span.

Because the college basketball postseason is single-elimination, the best teams frequently do not advance. But you have to believe the coaches at the top of this list, by winning the possession battle consistently, won’t be disappointed in the postseason forever.

I decided to cut the list off at 40 coaches because the list was starting to look a lot less elite. Tubby Smith has been more of a compiler at Minnesota than a winner. His teams have been ranked in the 40s, 50s and 60s nationally in his five-year tenure with the Gophers. Because they’ve never been terrible (even beating North Carolina and Purdue before things went south last year), his average places him at 39th nationally over the five-year span. But he has yet to have a single dominant season. Coaches with single great years (think Tom Crean) have too many losing years dragging down their numbers. But the coaches listed above have been remarkably consistent over the last 5 years.

Who to Hire?

You might think this type of list would be a good roadmap to hiring a new coach. But the problem is that many of these coaches are not in a hurry to leave. Mark Few is quite happy at Gonzaga thank you very much. And Brad Stevens has almost certainly turned down some attractive opportunities to stay at Butler.

Still, I think if I had a BCS opening, I would be running to offer BYU’s Dave Rose a huge contract. Not only has Rose posted great efficiency stats, his teams almost always play at a fun fast-pace. BYU’s trip across the country to beat Virginia Tech on Wednesday night might not mean a lot if Virginia Tech continues to struggle in the ACC, but it impressed me immensely. How many coaches could take their team from coast-to-coast and win a game where they shot 33%?

Steve Alford might also deserve another shot at a BCS gig. It isn’t that he can’t win at New Mexico or that the Lobos don’t pay well enough, but given the unstable membership in the MWC, he might welcome another opportunity to show his stuff in a top league once again.

Offense or Defense

As I have noted in previous years, there are a number of one-dimensional coaches on the list. Leonard Hamilton, Tony Bennett and Bruce Weber have all succeeded almost entirely by teaching defense. Meanwhile Mike Brey and Scott Drew depend on their offenses to carry their teams. Jamie Dixon is also a bit of a one-dimensional offensive coach. But it is still surprising how bad Dixon’s defense has been this season.

Here are the coaches with the top efficiency margins over the last 10 years:
