San Francisco 49ers quarterback Brock Purdy came out of nowhere to become an NFL superstar. That sudden rise to stardom came with a hefty adjustment period. Earlier this week, Purdy was a guest on the “Built 4 More” podcast,

That's the pitch made by SI's Grant Cohn, who breaks down the very specific math that says the 49ers shouldn't pay a penny more than that to Purdy. Cohn writes that a three-year, $97.5 million deal is the best business. That's because Purdy's other option, if he doesn't take the deal, adds up to $97.3 million.

Purdy was absolutely correct. Garoppolo suffered a Lisfranc foot injury and Purdy took over the reigns to the offense. Purdy and the 49ers went a perfect 5-0 in the regular season and Purdy led San Francisco to the NFC Championship Game.
