An athletic move tight end, Gyllenborg has the traits to be picked on Day 3, even though some inconsistencies show up on tape. Gyllenborg has added good muscle on his frame but is more suited for blocking in space than handling in-line action due to a lack of consistent tenacity at the point of attack. He has the potential to attack defenses vertically from the slot but is in dire need of better route-running fundamentals and catch consistency. Gyllenborg’s upside might be worth a swing, but TE3/4 could be his ceiling.
