LAS VEGAS (AP) — The Chiefs go as far as Patrick Mahomes takes them. The 49ers have Christian McCaffrey, Deebo Samuel, George Kittle and a star-studded group surrounding Brock Purdy. This Super Bowl will come down to the other side of the ball. Defense wins the Vince Lombardi Trophy on Sunday. Kansas City is seeking to become the NFL’s first repeat champion in 19 years. San Francisco is aiming for a record-tying sixth Super Bowl title. Mahomes, Travis Kelce and coach Andy Reid get most of the attention on the Chiefs, but defensive coordinator Steve Spagnuolo’s unit deserves plenty of credit for carrying the team during various points of the season when the offense was inconsistent and out of sync.
