The two seasons where ginobli started more than 60 games he was an all-star. Think it was pretty obvious by anyone with eyes that had the spurs started him he would have been a perennial all-star all-nba.
The vast vast majority of players his caliber or better throughout NBA history would not have accepted coming off the bench. He sacrificed his ego and pride bc he was the ultimate team player and all he cared about was winning.
