Kamal Martin out of Minnesota is a linebacker with good size (6’3”, 240 lbs — nearly the same size as Von Miller but a little lighter). Martin is a guy who can get away from blocks decently and is also a decent blocker.
With late-round picks, you are really looking for someone who could possibly make an impact at their natural position, but the later rounds are where teams look for special teams contributors.
There could be potential for Martin to be a contributor in a limited role on the defensive side of the ball. He is an outside linebacker, but as you know, the Broncos already have two stars at that position: Miller and Chubb. Both Miller and Chubb could be great mentors for Martin.
This from The Draft Network:
"“Kamal aligns as a 4-3 OLB for the Gopher defense. He brings average reactive athleticism to the LB position. He has good length and a sufficient amount of range which helps him be effective when dropping in space against the pass.”"
Dropping into coverage is something that Fangio has asked of his linebackers, primarily Miller. While I feel like that wasn’t the ideal way to use Miller’s talents, Martin could see the field when Fangio wants the defense to be in some package(s) that require this skill.
