Another great reason why Utah traded with the Cavs:
Statistically (based on results) the Cavs lottery picks are much more likely than normal to become 1st overall picks over the past 2 decades:
2003 - Lebron (22.5%)
2011 - Kyrie (2.8% - though it was technically the Clippers' pick!)
2013 - Bennett (15.6%)
2014 - Wiggins (1.4%)
That's 20% success rate when their actual odds were dramatically lower.
The Knicks and Mavericks are among a number of teams that have consistently lost the lottery - that consistently draft worse than their record.
An optimistic gambler might say we're due for the big win.
A pessimistic gambler would say we're cursed and happily trade picks for real players. (this was our strategy for years!)
