Cornerback: C.J. Henderson, Trevon Diggs
Over the last two seasons, Richard Sherman recovered from an Achilles injury and played through hamstring issues to once again become one of the NFL’s best cornerbacks. This gave defensive coordinator Robert Saleh a level of surety on one side of the field; things were not quite as consistent on the other. Ahkello Witherspoon was benched for performance issues on more than one occasion, and he allowed seven touchdown passes to just one interception. Emmanuel Moseley was better, especially in the postseason, but Saleh’s defense relies on cornerbacks who can excel more with their own execution than any particular schematic flexibility. Florida’s C.J. Henderson has the size, speed on the bounary, and route-matching ability to fit well in what Saleh wants to do. Diggs, the Alabama defensive back who’s also the brother of Vikings receiver Stefon Diggs, would also present an excellent physical prototype, though he might be available at the end of the second round. The 49ers could also try to take their two first-round picks and trade up for Ohio State’s Jeff Okudah, a sure top-five selection.
