In this hypothetical trade, the Rockets would turn Wood into Derrick White, Lonnie Walker, and a couple of other assets. White is older than Wood, meaning that he wouldn’t likely be a part of the Rockets' future. However, he is a talented two-way player with three years remaining on his contract and who could later be flipped for additional assets.
As for Walker, his role in the NBA now appears to be strictly that of a solid scoring guard who can also be a secondary playmaking option. While that may not necessarily appeal to every team, he’s only 22 and still has plenty of untapped potential. Also, Houston has shown a tendency to gamble on talent, including Kevin Porter Jr, and even signing a then relatively unproven Wood. Therefore, it's possible they could be intrigued by Walker.
Still, the centerpiece of the Spurs' offer would undoubtedly be their 2022 first-rounder. Currently, San Antonio has one of the worst records in the NBA. To add to that, they’re heading into an absolutely brutal stretch where they play 18 of their next 24 games against teams that made the playoffs or play-in last season. Therefore, it's possible that the Spurs pick ends up being a top 5 pick, though, in this proposal, that pick would be top 3 protected for 2022 and 2023 before turning into two seconds.
For the Spurs, Wood would give them a skilled offensive power forward/center who can get buckets in a number of ways. He can score in the post, especially by facing up and attacking his defender off the dribble. He can also be a knock-down spot-up shooter that can even hit step-back threes when handling the ball on the perimeter. Additionally, he gets easy points off of putbacks and is a lob threat.
On the defensive end, he may struggle to defend away from the basket, though he's displayed a decent ability to stay attached at the hip when guarding a driver and he is a legit shot blocker.
Additionally, a post-trade starting lineup of Dejounte Murray, Devin Vassell, Keldon Johnson, Wood, and Poeltl is better than the Spurs' current starting five and would have a solid balance of interior scoring, shooting, and defensive ability. As for Augustine, he'd mostly be a trade filler and could later be moved or even waived.
