The thing is, about 1% of college, division one players make the NBA each year. That's a rough estimate but I'd say it's pretty accurate. There are other players beyond that 1% of college players who are still great players, if you are in the top 2% of something I'd still say you are great, just not good enough.
Fact is, the NBA is a very hard league to make, incredibly hard. You can be a great basketball player and never, ever sniff the league. For whatever reason Herby doesn't get that.
White could make the NBA, it could happen, but the number are against pretty much any player to make the NBA. It's just that hard to do.
