This might be one of the worst lotteries ever, but the draft on the whole isn't bad.
I think in the Lottery you have 1 blue chip (Irving), 1 sure fire quality player who likely won't be a star (Williams), a few unknowns (the Euros and Kanter), and then a bunch of guys who would be mid to late first rounders in most other drafts.
I think this will be a draft where, if you are not in the top 2 picks, you will have as much chance of success with your pick at 3-10 as you will from 25-35. There are going to be a lot of guys in the lottery who are borderline rotation players at best, and potentially out of the league in 5 years, and there are going to be a lot of guys later in the draft who will have long, productive careers.
