McCaffrey's five catches remain the clearest separation. He also handled 15 total touches, produced 88 yards from scrimmage and stayed involved in the passing game. Black caught his only listed reception for five yards. The opener supports a complementary rushing role for Black; it does not establish an even split in the touches that tend to matter most for fantasy scoring.
Black is now a credible bench target where he is available, especially for managers protecting a McCaffrey investment or carrying an open developmental spot. One game does not make him a weekly starter, and another 14-carry day should not be assumed whenever San Francisco is favored.
Week 2 will be more revealing if the score stays close. Track Black's first-half snaps, two-minute work, third downs and red-zone touches. Early carries would support standalone value. Work concentrated after San Francisco builds a lead would keep his value closer to game flow and McCaffrey insurance.
Black has moved from preseason possibility to the active watch list. The next usage split will determine how much a manager should spend to get him.
