Due to the strike in 1981, the season was split into two halves and playoff seedings were determined using the winners from each half. The first half began on April 9 and ended June 11, while the second half started on August 10 and ended October 4. Overall standings are presented here for reference but were not used to determine playoff berths.

Projections are based on thousands of Monte Carlo simulations of the remaining seasons' schedule. They incorporate up to date player projections, current roster composition, playing time projections and the remaining schedule.
