Jimmy Garoppolo signs record 5-year deal with 49ers The 49ers announced Thursday they signed Jimmy Garoppolo to a five-year contract extension. The deal is worth $137.5 million, NFL Network's Mike Garafolo reported, per a source informed of the decision. The deal is the largest in NFL history on an average-per-year basis. Should have put the franchise tag on him made sure he was for real over course of a season then sign him to big contract. 5 starts and you give him this kind of money he has got to have a grin he can't wipe off his face.
