The conference semifinals have made history in several ways:
1. For the first time in NBA history, three 60+ win teams lost Game 1 of the same playoff round:
The 64-18 Cavaliers lost to the Pacers 121-119 on Sunday.
The 68-14 Thunder lost to the Nuggets 121-119 after blowing a 108-95 lead with 6:39 left on Monday
The 61-21 Celtics lost to the Knicks 108-105 in overtime after blowing a 75-55 lead with 5:47 left in the 3rd quarter on Monday.
2. For the first time in NBA history, all 4 road teams won Game 1 of the division/conference semifinals in the same season.

It's even more incredible how the Cavaliers blew an 81-61 lead with 6:51 left in the 3rd quarter and a 119-112 lead with just 48 seconds left to lose to the Pacers 120-119 and fall to 2-0 deficit as the No. 1 seed in the East.
4. During a remarkable three-day run that began Sunday, home court has proven to be no advantage, with road teams going a combined 6-0. The stretch has been bookended by Golden State victories that saw the Warriors, the seventh seed in the Western Conference, first topple the second-seeded Rockets in Houston in Game 7 of their opening-round series, then open the conference semifinals two days later with a 99-88 win in Tuesday's Game 1 in Minneapolis against sixth-seeded Minnesota.
