For years, the team by the Bay Area benefitted from having quarterbacks like Brock Purdy on rookie contracts. Now that negotiations with Purdy are underway, the 49ers need to plan around his potentially massive deal by cutting the fat elsewhere.

The $76 million deal heading George Kittle's way is an important line in the sand for the San Francisco 49ers.

NFL Network's Ian Rapoport reported on Tuesday that Kittle and the 49ers agreed to terms on a four-year, $76.4 million extension that will make him the league's highest-paid tight end. The 49ers entered the day with $39.4 million in cap space, not accounting for any potential changes to Kittle's cap number with his new contract.
