PORTLAND -- There wasn’t much to be learned from the result of Tuesday night’s preseason contest between the Trail Blazers and Suns at the Moda Center, which Phoenix won 114-112 in front of a crowd of 15,057, unless you were curious about which team’s third-string players were better shooters. While the final score didn’t reveal much about either team, there were takeaways to be had. There was Ed Davis, who started at power forward and was the rugged interior presence fans had come to revere before a shoulder injury ruined his 2016-17 season.“He’s got a bounce, he’s finishing around the basket, he’s getting offensive rebounds,” said Trail Blazers head coach Terry Stotts of Davis’ play. “He made a lot of good help side reads, particularly in the first half defensively. As I said after the first day or two of practice, he’s back to doing the things we know Ed can do.”Rookies Zach Collins and Caleb Swanigan, playing in the first real game, albeit preseason, of their careers at the Moda Center, looked as though they would be able to contribute this season in one way or another. In Swanigan’s case, he showed an ability to hit the NBA three — he went 2-of-2 from beyond the arc — while holding his own in the paint on the way to finishing with 18 points and six rebounds in just under 17 minutes. “Shooting is shooting, you’ve just got to know when to take a shot, when not to take a shot,” said Swanigan. “Basketball-wise, you get your first open shot, if you’re a good shooter, you shoot it. That helps your team. If you pass up a good shot as a good shooter, you may not get something better that possession.”
