Once it became clear that no team had leapfrogged the Lakers on Tuesday night — guaranteeing that the Lakers would keep the pick, which would have been sent to Philadelphia if it had fallen out of the top three — the first stages of a Ball-Laker union were underway. That union could yet be derailed by goings-on between now and draft day, including the potential for a Lakers trade. But for now, this pairing carries the odor of inevitability. In fact, some executives around the league have been concerned about their ability to get Ball in for a workout between now and the draft in June. With the Lakers keeping their pick, front offices with the potential to land in the top three have been bracing themselves for the possibility that Ball will simply refuse to work out for any team other than the Lakers.
