The 49ers’ secondary from a sheer numbers standpoint is their biggest offseason need. They have three cornerbacks under contract going into free agency and zero starters, and starting strong safety Jaquiski Tartt is set to hit unrestricted free agency. One player who could fit a number of vacated roles on San Francisco’s defense is TCU safety Trevon Moehrig, who was sent to the 49ers in Touchdown Wire’s first mock draft.

It’d be fascinating to see how the 49ers utilize Moehrig if they did wind up selecting him. Todd McShay also had him as a fit with San Francisco in his mock.

Traditionally Moehrig would fit the free safety role occupied by Jimmie Ward. He’s versatile and athletic enough to play high, but good enough in coverage to climb down and affect games closer to the line of scrimmage.

Doug Farrar expanded on Moehrig’s skill set in the TD Wire mock:

Moehrig spent equal time in the box, in the slot, and at free safety last season in TCU’s split-field coverage, and he was an eraser wherever he lined up. In three seasons with the Horned Frogs, Moehrig allowed 49 catches on 96 targets for 533 yards, 253 yards after the catch, five touchdowns, seven interceptions, and an opponent passer rating of 54.7.

While free safety doesn’t top the 49ers’ list of offseason needs, the Moehrig selection could be one that helps in multiple areas over the course of the next few years.

He could conceivably work in as the nickel corner right away should K’Waun Williams exit in free agency. Ward signed a three-year deal last offseason, but at the end of this contract will be 31-years old and San Francisco may be looking to move on to a younger option, at which point Moehrig could slide back to his natural position – much the same way Ward did after spending part of his career playing corner for the 49ers.

It’s hard to imagine with their list of needs that general manager John Lynch would target a safety prospect in Round 1, but a good athlete with Moehrig’s level of versatility could be difficult to pass up for a team that could use an injection of talent in the secondary.
