There's actually some merit to this thread. If Duncan is healthy, the Spurs are definitely under some pressure to win the le this season. They were the frontrunner for winning the championship all season. They had the best odds in Vegas of winning a le in quite some time. They used their cap space over the past few summers to re-sign their core in Duncan, Ginobili, Parker and Bowen, while adding key roles players around them. They will be capped out now for quite some time.
They are of course under pressure to win a le this season... Everyone expects the Spurs (with a healthy Duncan) to win the Championship.
