Nets’ Star Appears To Leak NBA Return Plan
So here's why I feel like this is solid information. I feel like Geiger probably has friends in the NBA and possibly heard some rumors from said players. So he had some real info and then Spencer Dinwiddie decided he'd clarify with the information he had.
So assuming this information is correct: The practice would start June 21st and final 5 regular season games start July 15th in "a bubble" which could be Disney World or Las Vegas. Possibly both locations.
