Jordan Mason, Aaron Jones, they played about equal snaps last week. ... So, he's going to go into the dub flex category, but he's going to go towards the bottom of it

Low-end flex play in a split backfield

Jordan Mason is splitting snaps equally with Aaron Jones. While the source considers Mason the superior runner, the lack of target volume and the split backfield make him a low-end 'dub flex' play for Week 2. He is viewed as a high-end handcuff who could see significant involvement if the 49ers build a large lead, potentially outperforming players like Tyler Allgeier or Chris Rodriguez Jr.
