 The NBA playoffs already promised to be the most challenging yet. They got a little tougher on Tuesday (Wednesday, Manila time) for the NBA’s top teams.   

Milwaukee  and Los Angeles lost their playoff openers, the first time both conference No. 1 seeds have been beaten by the No. 8s to start their postseasons since 2003.         

First, it was Giannis Antetokounmpo and the Bucks, unable to call upon what was one of the best defenses in the league.         

Then  came LeBron James and the Lakers, clanging 3-pointers off the rim to provide a steady sound in a mostly empty gym.         

So good for most of the season, the top seeds are having trouble in the bubble.       

here’s no home-court advantage to lose in this postseason at Walt Disney World, making it easier not to panic in what would normally be a tougher predicament.       

The Lakers  knew they were in against a tougher-than-usual No. 8 seed in the Portland Trail Blazers, who came back from the coronavirus-caused suspension of the season healthy and then played their way into the postseason by winning a play-in series.   

The Los Angeles Lakers  didn’t help itself in trying to slow down a hot opponent by shooting just 15.6% (5 for 32) from 3-point range and wound up losing 100-93.     

Milwaukee’s  problem was on the other end. The Bucks surrendered three 30-point quarters — and 29 in its best period — to the short-handed Orlando Magic in a 122-110 loss. That was an especially poor performance from a team that led the league in a number of defensive categories and held opponents to a league-low 41.4 shooting percentage. Orlando made 49.4%.       

Neither team can blame its MVP candidate. Antetokounmpo had 31 points, 17 rebounds and seven assists. James had 23 points, 17 rebounds and 16 assists, the first 20-15-15 game in NBA playoff history.     

But neither team has looked particularly sharp in Orlando. They had arrived at the restart well ahead of their competitors for the No. 1 seeds and were focused more on staying healthy than getting wins in the eight seeding games leading into the playoffs.     

They couldn’t turn things around when things became serious and by the time the day was done, it was the first time both No. 1s lost since Orlando knocked off Detroit in the East and Phoenix beat San Antonio out West in 2003.
