1. every single year, hyped high school players don't live up to their hype when they get to college.
2. every year, hyped college players don't live up to their hype when they get to the NBA
3. every year, hyped NBA rookies don't live up to their hype in subsequent years.
Anyone who are convinced that there are 6-7 generational, change a franchise future, players in that draft, doesn't understand these facts. There's reason the draft is often referred to as a crapshoot. I don't know about other mocks, but one I just looked at has 4 of top 7 picks as players that haven't stepped on even a college floor yet.
Will there be an all star or 3 come out of the draft? It looks like a safe bet, but when I look at the past 10 years of "change a franchise's fortune" type players, I see Lebron (how did Cavs fortunes do with that?), KD, CP3 (how did NOLA's fortunes do with that?), Dwight (how did Orlando's fortunes do with that?), so even if you're lucky enough to get one of them, there's a good chance you had to be so bad that you can't keep them long enough to actually win anything. Then you're stuck building from scratch again.
