49ers signed No. 18 overall pick S Eric Reid to a four-year contract.
Niners GM Trent Baalke traded up to land coveted LSU alum Reid, sending Dallas the Nos. 31 and 74 picks. Although Reid lacks ideal hip fluidity and change of direction, the 49ers won't ask him to cover receivers one on one. He's a rocked-up, straight-line speedster who'll play in single-high and two-deep safety looks while Donte Whitner focuses on plugging the run in the box. Reid will replace Dashon Goldson, who recorded 69 tackles and three picks in 2012.
