The San Francisco 49ers are 3-4, and while they aren’t out of the race for the NFC West, and could very well still win it, one thing has become very clear this season. Brock Purdy will never be the franchise quarterback for the 49ers. Purdy is eligible for a contract extension with one year left on his rookie contract after this season. It’s something the 49ers have to keep in mind, but if they extend him, it will set their franchise back.
