OPC’s 3rd Day Prospects – Justin Zimmer, DL Scouting Report in NFL Draft, Scouting, and Free Agent Talk Posted March 18, 2016 Do you think he could add weight and perform at NT in a 3-4? He seems to be strong enough. Viewing his reel he also seems to understand leverage. Do you know how long his arms are? If he is short but long arms he could play the 5 without issue. I like Dean Lowry and Joel Heath as possible late round/FA 5 techniques but Lowry has short arms for his height (6'6).
