Consider this - In the past 14 months, the Spurs have moved on from: DDR, LMA, Patty Mills, Rudy Gay, Derrick White, Drew Eubanks, Bryn Forbes (all arguably key rotation players, at least as far as the Spurs FO were concerned) and shipped out or waived Thad Young, Satoransky, Hermangomez and Dragic.
They will soon make decisions on: Lonnie Walker, Romeo Langford, Richardson (and probably Poeltl, based on value and desirability), to whether they will still be with the team next year...
DJ has solidified himself as an all-star talent, KJ continues to show that his shooting isn't a fluke, and Primo is getting key rotation minutes as a rookie for a team that rarely makes that kind of commitment...
This season has been an overwhelming success...and will continue to be whether they make or miss the play-in/playoffs.
This team may have built a reputation as a stubborn, antiquated, loyalty driven franchise (and deservedly so considering their past successes), but this season isn't one of them.
The Spurs seem to be cognizant of where they are, (finally), how their players are projecting, what talent is available come draft and likely, the flattened structure after pick 4. They couldn't care less what the mocks say.
They have their draft board.
If they want to make a run for the play-in, I say go for it.
