Here´s the NFL´s scouting report on Perryman:
STRENGTHS
Burly, stout, old-school linebacker build. Wants to hit and brings his pads with him when he delivers a blow. Delivers a jarring punch into oncoming offensive linemen on second level. Defends his area of turf and sees past blockers, keeping his eye trained on the play. Is able to disengage and shed blockers. Plays low and with leverage. Once he diagnoses, can trigger into gaps and disrupt. Expected to be productive special-teams player at the next level.
WEAKNESSES
Not a twitchy athlete. Takes time to gear up after changing directions and can struggle to tackle jitterbug runners in space. Heavy-legged mover in space and struggles to make plays outside of his assigned area. Lacks coverage traits and is a liability in man coverage. Short levers won't allow him to leverage blockers as a pass rusher. Slow to get off his spot and burst laterally, which causes him to miss some tackle opportunities.
SOURCES TELL US
"He's physical and plays angry at the point of attack. He's the type of guy you like having on your team because he brings toughness to practice. He's going to lay the wood to ball carriers when he gets a chance but college teams were already finding ways to go after him in the passing game." -- AFC East regional scout
"I have a little higher grade on Perryman than I probably should, but we like thumpers and badasses inside and he's both." -- AFC director of scouting

BOTTOM LINE
Early down linebacker who can make plays against the run but will struggle if isolated in coverage. Perryman is a lunch-pail worker who enjoys the physical part of the game. Can be a highly productive NFL player but ceiling looks to be limited.
CBS Sports (where you´ve got the more positive scouting report from) has Perryman ranked 74th overall and as the 3rd best ILB, 37 spots behind Eric Kendricks.
