The Spurs gifted that a 10 year $27.1M career for being a career garbage time player.
To add fuel to the fire, the Spurs had a chance to amnesty him and use the money to improve the team and they chose to keep him and re-up him in free agency instead.
Pop has created the ball-dominant Kawhi we have had the last couple of seasons. He is also extremely effective off the ball. That's what he did before Pop reverted to 90's ball.
The Rockets were a dysfunctional hot mess with Ty Lawson running the point and was in the process of bringing down the whole team when Houston made the switch to put Harden back at the point and benching that hot mess of a player before eventually trading him to Indiana. If I may play devils advocate for a moment, Kawhi is a ball dominant player too. What makes you think he'll be a good fit next to Leonard? They already have two ball dominant players (LMA, Leonard) in the starting lineup.
