Hard to disagree. We've had only one BN winter since 2011-12 (2014-15), and that was largely due to the last two weeks of February. Even 2013-14, the infamous winter of the Polar Vortex, finished slightly AN due to a warmer than normal December. 2011-12, 2012-13, and 2018-19 were consistently AN. And then you have 2015-16, 2016-17, and 2017-18 which all finished AN due to a month of torching (December in 2015, February in 2017/2018).
2017-18 was the closest to a BN winter in recent years, but the February torch resulted in finishing AN.
