6'0", 210. Boston has just completely gone under the radar here. Haven't seen many mentions of him but love the thought of the 49ers adding this guy. He is very strong in coverage, can play cornerback or safety and would give the 49ers a hell of a tandem if Whitner doesn't re-sign. Even if he were to re-sign, Boston could aid as depth at safety as well as playing the slot cornerback. He has enough speed to cover the deep portion of the field and is a generally solid tackler. He's had 4 interceptions in each of the past 2 seasons. He does well in attacking the ball in the air and has solid size for the position as well.
