Talent is not JUST talent.
Rose is a shell of his former self - he only played half a season, and for that half a season he was still finding his feet - trying to rekindle whatever game he could after not playing basically since 2011. Noah's degenerative osteoarthritic knee issues and laundry list of other health problems had him looking Roy Hibbert's ugly sister on the offensive side of the ball. And although Gasol had an impressive regular season, his age eventually caught up with him; playing 22 mins in Game 3 before succumbing to a hamstring injury, missing Game 4 and Game 5 and only playing 24 mins of Game 6 while still struggling with the injury.
That talent is not enough to win.
When did the Spurs win while going through similar problems, with a bench of fringe NBA players and role players that failed to fulfill their roles?
