Per:
https://www.si.com/nba/2017/05/05/nba-draft-combine-full-player-list-attendeesAs is common each year, several of the expected top-of-the-lottery players will NOT be attending:
Lonzo Ball, Josh Jackson, Jayson Tatum, Malik Monk, Dennis Smith, Jr., Lauri Markkanen and Jonathan Isaac all have indicated they will not attend.
Perhaps more notable, is that prospective #1 overall pick Markelle Fultz currently IS expected to attend.
That's obviously a risky move. By being measured against and scrimmaging with guys who may not even be expected to be drafted, let alone at the top of the first round, Fultz risks being 'exposed' or overshadowed and having his stock drop.
Yet somehow, just taking that risk might make me like him more.
Of course, he may just show up for measurements and interviews, like Jaylen last year. That clearly did not hurt Jaylen.
