The NBA playoffs should be entertaining, as they always are. Just don’t count on the basketball being as good as usual. Not after a truncated season during which the injuries were too frequent, the practice time too scarce, to allow teams to peak for the postseason. “It’s been much more devastating to culture and to establishing momentum for sure, for all of us,” Spurs coach Gregg Popovich said. “And I definitely think that, I hate to say it but it’s the truth: There’s no way it can be the best basketball for all the teams.” LeBron James was a spectator the night the Lakers raised the banner for the championship they won last year, as he was for most of the second half of the season because of an ankle injury.
