What did we learn about the Cleveland Cavaliers in the team's disappointing season debut vs. PHI?

The Cleveland Cavaliers opened their 2026-27 season with a disappointing 114-106 loss to the Philadelphia 76ers, blowing a 29-point lead in a game that raised some familiar concerns about this championship-hopeful roster.
