Report: NBA faces bumps in final effort to end 1-and-done

The NBA and the Players' Association continue to work towards ending the one-and-done rule, but are facing challenges as they near an agreement.

League commissioner Adam Silver is pressing NBPA director Michele Roberts on two issues: player agents are required to provide all teams medical information on high school prospects, and the league wants to mandate player attendance and participation in the pre-draft combine, sources tell ESPN's Adrian Wojnarowski.

"We're investing millions of dollars into players who we'll now have even less information about coming out of high school, and we should have the right to have all the information available on who we are selecting," one general manager said, according to Wojnarowski.

Agents are reportedly uninterested in releasing medical information for potential prospects and the union is so far maintaining their position unless the NBA gives back elsewhere.

Not providing medical information is a tool commonly used by agents to leverage prospects draft positioning and push them towards a preferred destination. Front offices are generally hesitant to select a player without knowing their injury history.

"Some organizations are run better than others," an agent told Wojnarowski. "A lot of success comes from a player getting into the right situation at the right time. If I can do something that influences that, why would I give that up?"

The one-and-done rule reportedly won't change until 2022. However, the Association will be opening a "professional path" system for elite high school prospects that offers $125,000 contract if they choose to forgo college and enter the NBA's G League.
