Fantasy football Week 7 stock watch: Buy low right now on Brock Purdy, not so fast on Cam Skattebo

In a Week 7 fantasy football stock watch analysis, CBS Sports advises managers to buy low on San Francisco 49ers quarterback Brock Purdy, arguing that the injuries to his offensive weapons are temporary and his value will rebound. Conversely, caution is urged on Giants rookie running back Cam Skattebo due to a crowded New York backfield that could limit his opportunities. The piece also addresses the fantasy outlooks of wide receiver Nico Collins and running back Derrick Henry.
