I think he's playing too much Pokemon Go too be plugged into an NBA team during early July.
This guy looks like a wacko, but if you go through his Twitter feed, it appears that he does make some pretty accurate predictions that are more than the "so and so will sign here" type variety.
Like for example, he calls the Horford signing the day before it was announced and actually states that one of the reasons Horford signed with us is that Horford heard that D12 was going to sign with Atlanta.
A few days after the Horford signing came out, reports said that Horford didn't want to play D12.
