Most of the field sucks and has no shot to win a title that's why. Sure some teams may upset some contenders but they"ll likely lose right after.Who would have thought "taking the field" is a bad bet?
UNC 2017, Duke 2015, Louisville 2013, UK 2012, Duke 2010, UNC 2009, KU 2008 are all recent champions who would've made anyone money if they picked them along with 2 other teams that year vs the field to win a championship.
The UConn titles made everyone believe that "any team" has a chance when they really don't.
