Singletary or Breida in a Trade

Both are keepers (5th round value next year). Who would take?

If all things go as planned singletary should be the lead back. Niners should still be the same share workload but still valuable. I can see singletary getting 15+ most games. I think breida is capped except for the td and multi td games. I’m on the singletary side because of the likely number one and sole backfield. Breida is under a good coach that has a good system going if you trust that more long term.
