THE CASE FOR PURDY
James Cook is entering his prime and just posted a breakout second season with the Bills. He offers elite receiving upside and is locked into a high-powered offense. Buffalo's lack of backfield competition keeps his touch floor safe. Cook's youth and role make him a valuable RB2 with RB1 weeks possible.

Brock Purdy is the efficient engine behind San Francisco's loaded offense. He finished as a top-10 fantasy QB, buoyed by elite weapons and coaching. Purdy is only 26 and has job security for at least the next 2-3 years. In Superflex, stable young QBs are dynasty gold.
