They are not comparable. First, the Packers didn't keep Bradford at OLB - they tried moving him to ILB. Second, Landry not only has more length but also tested much better at the combine: Landry: 4.64 (40), 6.88 (3-cone), 4.19 (short shuttle) Bradford: 4.76 (40), 7.25 (3-cone), 4.30 (short shuttle) Scouting reports also say that Landry has elite burst, ability to dip and rip, and bend the edge. Landry also forced at least 10 fumbles in his career. There's a reason Bradford lasted until the 4th round, and why Landry will go in the first. Landry's comp is closer to James Harrison than Bradford. Third... how do you know how much effort Bradford put into learning his position and adjusting to the league, and how do you know how much effort Landry will put in?
