3. Roby is still young with untapped, raw talent
The biggest reason the Spurs took just two days to claim Roby off of waivers is likely his untapped potential. If there's ever going to be a year when San Antonio can afford to experiment with different lineups and talents, this is going to be it.
Isaiah has had several standout performances in his three seasons in the NBA, including a monster game against the Portland Trail Blazers earlier this year. Any time you can score 30 points in an NBA game, that's a strong indication you have some serious tools that can be utilized.
The Spurs saw Roby's effectiveness firsthand last February, when he scored 17 points, pulled down 12 boards, and tallied three steals in a 114-106 San Antonio victory. It's not hard to see what Roby could offer with some work-shopping in a new developmental system, and the Spurs have one of the best in the world.
Josh Giddey, who will likely be a star in this league very soon, praised the Spurs for their acquisition of Roby on Twitter:
At best, Roby could become a an effective role player in San Antonio if he polishes his game. At worst, he'll be insurance on a roster full of young, promising talent that'll be emphasizing growth more than wins this season. Not a bad risk at all.
