I think Kaelon Black will be the top backup running back in San Francisco this season... the lead ball carrier averaged 85.3% of the team's RB carries in every McCaffrey-less game. That includes six games of at least 90% of the carries and three times at 100%. Basically, if McCaffrey goes down, one guy will get the work. And while the 49ers' recent history of Day 2 RB picks is spotty at best, I fully expect the first crack at that work will go to Black.
