Video: Top 50 Running Back Rankings & Tiers (Updated)
Zack Charbanet is slowly ramped up. Charbanet is probably the running back one in this backfield. But also, there is no certainty because Zack Charbanet is coming back from his torn ACL faster than any running back since 2012 with Adrien Peterson.

Returning from torn ACL faster than any RB since Peterson; health uncertain.

Charbonnet is expected to be ramped up slowly after returning from a torn ACL. He is likely the lead back in the backfield, but there is significant concern about his recovery given he is returning from ACL injury faster than any running back since Adrian Peterson in 2012, creating uncertainty about his health trajectory.
