Following the NBA Combine, a lot of players — notably at the guard spots — saw their stock plummet. For instance, the dynamic playmaking Sharife Cooper measured at 6’ feet on the nose. There is some speculation that he may even drop out of the First Round entirely because of his swing-for-the-fence style of reckless play and tiny frame.
Another thing hampering the draft this year is just relative lack of guards. If you want wing players, the draft is loaded. If you want a three-and-D ballhandler with a nice outside stroke, your options are very limited
So, perhaps with competing player evaluations checking in a lot lower than many expected, being generally adored by GMs, and a good overall combine, it should not have been a surprise that Josh Primo, long bandied about as a marginal First Rounder, decided to test the NBA waters.
