If you look at the ESPN schedule where it lists how many tickets for what price, you'll find:
186 tickets remaining for Pacers - Cavs for as low as $34
167 tickets remaining for Utah - Oklahoma City for as low as $31
357 tickets for Minnesota - Houston for $77
1,000+ tickets remaining for tomorrow's games in San Antonio and Miami. Tickets for $46 for the Portland - New Orleans game tomorrow.
Not really a big deal.
