# March Madness Data This repo contains JSON files for all the NCAA brackets from 1985–2017. ## Results ### Sums of Seeds After #16 seed UMBC became the first to beat a #1 seed, I was curious what the highest sum of seeds in a game was. This was harder to find out than I expected, so I grabbed some data from Wikipedia and found the answer. It's 25! ``` (1989) 25: Minnesota 11 vs 14 Siena (1991) 25: Eastern Michigan 12 vs 13 Penn State (1991) 25: Temple 10 vs 15 Richmond (1991) 25: Connecticut 11 vs 14 Xavier (1992) 25: New Mexico State 12 vs 13 Southwest Louisiana (1993) 25: George Washington 12 vs 13 Southern (1997) 25: Texas 10 vs 15 Coppin State (1998) 25: Washington 11 vs 14 Richmond (1998) 25: Florida State 12 vs 13 Valparaiso (2001) 25: Georgetown 10 vs 15 Hampton (2001) 25: Gonzaga 12 vs 13 Indiana State (2008) 25: Villanova 12 vs 13 Siena (2008) 25: WKU 12 vs 13 San Diego (2009) 25: Arizona 12 vs 13 Cleveland State (2011) 25: Richmond 12 vs 13 Morehead State (2012) 25: Xavier 10 vs 15 Lehigh (2012) 25: South Florida 12 vs 13 Ohio (2013) 25: Mississippi 12 vs 13 La Salle (2014) 25: Tennessee 11 vs 14 Mercer (2015) 25: UCLA 11 vs 14 UAB (2016) 25: Syracuse 10 vs 15 Middle Tennessee (2018) 25: UMBC 16 vs 9 Kansas State (1997) 24: Chattanooga 14 vs 10 Providence (1993) 22: Temple 7 vs 15 Santa Clara (2012) 22: Florida 7 vs 15 Norfolk State (2013) 22: Wichita State 9 vs 13 La Salle (2013) 22: San Diego State 7 vs 15 Florida Gulf Coast (1986) 21: Cleveland State 14 vs 7 Navy (1998) 21: Rhode Island 8 vs 13 Valparaiso (2011) 21: VCU 11 vs 10 Florida State (2014) 21: Dayton 11 vs 10 Stanford ``` All the 25s are in the Round of 32. This happens whenever there are two first-round upsets in the same part of the bracket. You can't get a higher sum than 25 until the third round or later, and this has yet to happen. The closest was 14 Chattanooga vs. 10 Providence in 1997. **Sweet 16**: ``` (1997) 24: Chattanooga 14 vs 10 Providence (2013) 22: Wichita State 9 vs 13 La Salle (1986) 21: Cleveland State 14 vs 7 Navy (1998) 21: Rhode Island 8 vs 13 Valparaiso (2011) 21: VCU 11 vs 10 Florida State (2014) 21: Dayton 11 vs 10 Stanford (2016) 21: Gonzaga 11 vs 10 Syracuse (2002) 20: UCLA 8 vs 12 Missouri (1990) 18: Loyola Marymount 11 vs 7 Alabama (2001) 18: Temple 11 vs 7 Penn State ``` **Elite Eight** ``` (2000) 15: North Carolina 8 vs 7 Tulsa (2002) 15: Indiana 5 vs 10 Kent State (1990) 14: Arkansas 4 vs 10 Texas (1997) 14: Arizona 4 vs 10 Providence (2000) 14: Wisconsin 8 vs 6 Purdue (2002) 14: Missouri 12 vs 2 Oklahoma (1986) 12: Kentucky 1 vs 11 LSU (1990) 12: UNLV 1 vs 11 Loyola Marymount (1994) 12: Boston College 9 vs 3 Florida (2001) 12: Michigan State 1 vs 11 Temple ``` **Final Four** ``` (2011) 19: VCU 11 vs 8 Butler (2006) 14: Florida 3 vs 11 George Mason (1986) 13: LSU 11 vs 2 Louisville (2000) 13: Florida 5 vs 8 North Carolina (2016) 11: North Carolina 1 vs 10 Syracuse (1985) 10: Villanova 8 vs 2 Memphis State (1992) 10: Michigan# 6 vs 4 Cincinnati (2010) 10: Michigan State 5 vs 5 Butler (2013) 10: Louisville 1 vs 9 Wichita State (2014) 10: Wisconsin 2 vs 8 Kentucky ``` **Finals** ``` (2014) 15: Connecticut 7 vs 8 Kentucky (2011) 11: Connecticut 3 vs 8 Butler (1985) 9: Georgetown 1 vs 8 Villanova (1988) 7: Kansas 6 vs 1 Oklahoma (1992) 7: Duke 1 vs 6 Michigan# (1989) 6: Seton Hall 3 vs 3 Michigan (2000) 6: Florida 5 vs 1 Michigan State (2002) 6: Maryland 1 vs 5 Indiana (2010) 6: Butler 5 vs 1 Duke (1991) 5: Kansas 3 vs 2 Duke ``` ### Craziest Final Four Or what was the craziest final four (i.e. highest sum of seeds)? It was 26, in [2011][]. The least crazy was [2008's final four][2008], the only with four 1 seeds. ``` 26 2011 Kentucky (4) Connecticut (3) VCU (11) Butler ( 8) 22 2000 Florida (5) North Carolina (8) Michigan State ( 1) Wisconsin ( 8) 20 2006 LSU (4) UCLA (2) Florida ( 3) George Mason (11) 18 2014 Florida (1) Connecticut (7) Wisconsin ( 2) Kentucky ( 8) 18 2013 Louisville (1) Wichita State (9) Michigan ( 4) Syracuse ( 4) 15 2016 Villanova (2) Oklahoma (2) North Carolina ( 1) Syracuse (10) 16 2018 Loyola–Chicago (11) Michigan ( 3) Villanova ( 1) Kansas ( 1) 15 1986 Duke (1) Kansas (1) LSU (11) Louisville ( 2) 13 2010 Michigan State (5) Butler (5) West Virginia ( 2) Duke ( 1) 13 1992 Duke (1) Indiana (2) Michigan# ( 6) Cincinnati ( 4) 12 2017 South Carolina (7) Gonzaga (1) Oregon ( 3) North Carolina ( 1) 12 1990 Duke (3) Arkansas (4) Georgia Tech ( 4) UNLV ( 1) 12 1985 Georgetown (1) St John's (1) Villanova ( 8) Memphis State ( 2) 11 2005 Illinois (1) Louisville (4) North Carolina ( 1) Michigan State ( 5) 11 1996 Massachusetts (1) Kentucky (1) Miss.

It's all in `data/YYYY.json`. For example: ```json { "year": 1997, "regions": [ [ [ [ { "round_of": 64, "seed": 1, "team": "North Carolina", "score": 82, }, { "round_of": 64, "seed": 16, "team": "Fairfield", "score": 74 } ], ... ], ... ], ... ], "finalfour": [ [ [ { "round_of": 4, "seed": 1, "team": "North Carolina", "score": 58 }, { "round_of": 4, "seed": 4, "team": "Arizona", "score": 66 } ], [ { "round_of": 4, "seed": 1, "team": "Minnesota*", "score": 69 }, { "round_of": 4, "seed": 1, "team": "Kentucky", "score": 78 } ] ], [ [ { "round_of": 2, "seed": 4, "team": "Arizona", "score": 84 }, { "round_of": 2, "seed": 1, "team": "Kentucky", "score": 79 } ] ] ] } ``` - There are four regions. - Each contains an array of four rounds. - Each round contains an array of games. - Each game is an array of two teams. - Each team is an object with `round_of`, `seed`, `team` and `score` keys. If you're working in Python, you can find some helper functions in `utils.py` and some example code in `find_highest_seeds.py` and `craziest_final_four.py`: $ ./craziest_final_four.py data/*.json 26 2011 Kentucky ( 4) Connecticut ( 3) VCU (11) Butler ( 8) 22 2000 Florida ( 5) North Carolina ( 8) Michigan State ( 1) Wisconsin ( 8) 20 2006 LSU ( 4) UCLA ( 2) Florida ( 3) George Mason (11) 18 2014 Florida ( 1) Connecticut ( 7) Wisconsin ( 2) Kentucky ( 8) 18 2013 Louisville ( 1) Wichita State ( 9) Michigan ( 4) Syracuse ( 4) ... ## Updating the data To regenerate (or update) the data, you'll need Python 3.6 or later. Set up your virtual environment and run: pip install -r requirements.txt ./extract_wiki_source.py pages/*.html ./extract_bracket.py pages/*.wiki mv pages/*.json data/ To add a new year, use `curl` to put a new HTML file in `pages/YYYY.html`. You can use the URLs in `urls.txt` as a template.
