With the desire still strong among the eight teams not invited to the NBA’s restart to avoid an eight-month layoff between formal group activities, Chicago has emerged as a potential landing spot for a second “bubble” environment, sources confirmed. Significant hurdles remain for the eight teams to gather in one city, but sources told NBC Sports Chicago that Wintrust Arena has emerged as a potential host for the group activities if those hurdles are cleared. The arena is connected to a hotel, which would make meeting the strict safety protocols that the league and players association desire more feasible.
