Currently, the teams with the three worst records have an ascending chance of winning the No. 1 pick, including (No. 3) 15.6 percent, (No. 2) 19.9 percent and (No. 1) 25 percent.
The NBA's proposal would flatten those odds, and give the three teams with the worst record the same percentage of earning the No. 1 overall pick, league sources said. Now, the worst record to the fifth-worst record has a gap of 25 percent to 8.8 percent, but new legislation would tighten that difference significantly, league sources said.
For example, the fifth-worst team would only have a few percentage points less than those teams with newly equal odds among the three worst teams, league sources said.
