George Kittle, the standout tight end for the San Francisco 49ers, has secured a hefty four-year contract extension worth $76.4 million, with $40 million guaranteed. This positions him as the highest-paid tight end in the NFL. Kittle's impact extends beyond his receiving capabilities; he excels as a blocker, making him invaluable to the 49ers' offense. His leadership in the locker room and on the field is undeniable, and the franchise aims for him to retire as a lifelong 49er.

Additionally, the 49ers added veteran offensive tackle DJ Humphries, who brings experience despite recent injury challenges. The team continues to focus on bolstering their roster after the NFL Draft, with a particular emphasis on improving their offensive line depth. The discussions highlight the critical roles Kittle and Humphries are expected to play as the 49ers prepare for the upcoming season.
