Epenesa has zero experience in coverage, while his burst and straight line speed have improved I doubt his agility and COD skills are up to OLB par.
I can’t see a position change; having him cut 25 pounds in hopes they can mold him into a passrusher who has both natural strength and some newly found bust seems much more likely.
Cover 1 did a phenomenal analysis on his development, Epenesa isn’t the player he was in college, he legitimately has some speed rush potential now.
