The San Francisco 49ers made another offseason addition in free agency. It's another player who isn't liable to move the needle on their chances of winning a Super Bowl. NFL Media's Cameron Wolfe on Monday reported the 49ers are signing former Miami Dolphins defensive back Siran Neal to a two-year contract.

Hoping to snap their eight-year drought without a playoff win, the Pittsburgh Steelers are signing a veteran safety who knows what it takes to advance in the playoffs after winning two Super Bowls as a member of the Kansas City Chiefs.

Defense wins championships, and it appears the Pittsburgh Steelers aren't done adding dynamic playmakers to their unit, as two-time Super Bowl champion and former Chiefs FS Juan Thornhill is coming to the Steel City on a one-year contract, as reported by Ian Rapoport and Mike Garafolo.
