The 49ers are seeking a lucrative extension with Brock Purdy. His teammate, George Kittle, has given him advice about negotiating with the team.

George Kittle’s got his own contract extension with the 49ers finalized last month, and he’s had advice for Brock Purdy about talks that could take much longer.

George Kittle agreed to a four-year contract extension last month and the way that it came together left Kittle feeling pleased about the process.
