If we're going with semantics, I wouldn't call the roster in 96-97 weak. It was injuries, not lack of talent, that did the Spurs in that season.
This is certainly looking like the weakest Spurs roster, talent-wise, in decades. The Spurs have had at least a borderline All-Star level talent on the roster every year since Robinson joined. This includes DeRozan and Aldridge in recent years. The only way I can see the Spurs getting an All-Star this year is if Murray or White makes a huge leap and starts putting up big numbers, and I don't see that as being very likely at all.
