The worst record right now has 18 wins, which is a lot higher than years past at this point.
I mean these are the final win totals for every team at or below 25 wins the last few seasons
2017 - 20, 24
2016 - 10, 17, 21, 23
2015 - 16, 17, 21, 25
2014 - 15, 19, 23, 25
2013 - 20, 24, 25
2012* - 8.69, 24.85 (extrapolated to a full season)
2011 - 17, 19, 22, 23, 24, 24
2010 - 12, 15, 25
So only twice since 2010 has the worst team even had 20 wins (one of those was last year). I would expect every team to have at least 20 wins this year. So the reality is, there are a lot of bad teams, maybe even more than typical, but there are no super terrible teams, which just makes for a lot more parity.
