The Mavericks have clinched their second NBA Finals appearance with their 4-1 series win over the Thunder. They will now sit and watch the Bulls and Heat play Game 5 of the Eastern Conference finals. If the Heat win, the 2011 NBA Finals will start on May 31 in Miami. If the Bulls win, the Finals will begin on June 2 regardless of results in the rest of that series. Here are the two alternative schedules set by the NBA. Best of seven (2-3-2 format)
