The 49ers have lost defensive ends Justin Smith to retirement and Ray McDonald was cut.  So they will need to add more options to the defensive line.  Texas’ Malcolm Brown could play defensive end or nose tackle for the 49ers and provide them with more depth. <b>LW: –</b>. Defensive Tackle. Texas. Malcolm Brown. 15. player. 42

10. The Texans signed Rahim Moore at free safety but their Strong Safety D.J. Swearinger struggled last season.  Alabama’s Landon Collins is the top safety in the draft and can come in and bring some competition and depth to the Texans secondary. <b>LW: –</b>. Strong Safety. Alabama. Landon Collins. 16. player
