Side by side

In 2025 Brock Purdy scored 20.8 PPR points a game and Zach Charbonnet 11.3, 9.5 a game between them.

Brock Purdy finished QB24 and Zach Charbonnet RB24, which are two different ladders.

Brock Purdy is a quarterback and Zach Charbonnet a running back, so the question is which slot you fill first rather than which of them is better.

Byes and availability

Brock Purdy is off in Week 8 and Zach Charbonnet in Week 11, so either can cover the other's bye.

What would change the answer

11.4 points a game is the entire case. The market restates it every week, and a line that moves moves the order with it.

The draft market is the half that is missing: when live drafts hold these two again they can order them differently from the projection, and this page will follow the drafts rather than the market-based projection when they do.
