If the NBA is able to come back, it will give teams like the Milwaukee Bucks just under a month to get ready.
According to ESPN, the NBA has developed a 25-day program for players to get ready for the season. It incorporates over a week of individual workouts to maintain social distancing measures before two weeks of full team practices would begin. The reason for the drawn out schedule is to make sure players do not get injured after the long lay-off, though Brian Windhorst from ESPN reports that some team executives would rather see the league take a full month to ramp up just to be sure.
Prior to the COVID-19 layoff, the Bucks had a stranglehold on the Eastern Conference lead and were NBA title contenders.
