There may not be opportunities for individual workouts with teams ahead of the draft. The Portsmouth Invitational Tournament, a haven for middling prospects, has been canceled; the combine, where many of the top players are evaluated, remains in limbo. Teams will have to find different ways to do pre-draft assessments. “The whole league is watching video,” Pistons senior adviser Ed Stefanski told The Detroit News. “We’ve seen some (of the top prospects). Everyone has a bank of information on players, so we’re all in the same boat.”
