PREVIEW: The San Antonio Spurs travel to Portland's Moda Center on Wednesday night with the Trail Blazers opening as 2.5-point favorites in an NBA Cup showdown. Portland enters the matchup at 2-1 in group play and tied with Denver atop West Group C, while San Antonio sits at 1-1. The Spurs face significant injury concerns with Victor Wembanyama sidelined for multiple weeks due to a calf injury and Stephon Castle expected to miss a couple of weeks with a hip issue. Despite missing key contributors, San Antonio has leaned heavily on De'Aaron Fox, who has scored at least 26 points in four straight games. The Spurs appear to have a defensive advantage over Portland, which has allowed 122 or more points in six of their previous seven contests. The Trail Blazers are dealing with their own injury complications, as Jrue Holiday has missed six games and will sit out for at least a couple of weeks, while Shaedon Sharpe is questionable with a calf injury. Portland scores 116.2 points per 100 possessions and allows 118.2 points in return, suggesting a squad struggling to maintain consistency on both ends of the floor. San Antonio, meanwhile, registers 118.4 points per 100 possessions while holding opponents to just 112.3 points, positioning them as the more efficient team heading into this Western Conference matchup.
