CB Byron Jones (Cowboys)
With their cap space evaporating rapidly, the Cowboys probably won’t be able to keep Jones despite the fact he’s arguably their best defensive player. For the 49ers, they’d scoop up a 27-year-old corner who can start right away, and take over for Richard Sherman (who’s in the last year of his deal) once he exits. The 49ers need to start stocking their roster to prepare for life without Sherman, and doing so with a Pro Bowl caliber talent would be a good way to ensure San Francisco’s pass defense remains one of the best in the league.
