WEAKNESSES: Needs to add some muscle, particularly if he's going to play on the interior at the next level, as he simply doesn't possess the natural strength to compensate for his lack of girth. Comes off the line too upright, and is easily knocked back when he does. Absorbs too much impact with his chest or shoulder, and at times will drop his head when engaging defenders in space. Exhibits only marginal fluidity in space, and wastes motion when asked to break down and redirect. Doesn't target decisively on the run, and lacks commitment when faced with multiple rushers.
COMPARES TO: Adam Grant, OT, Buffalo Bills - Quessenberry is still developing, but he's beginning to show versatility that reminds me of another converted tight end - former UDFA, Adam Grant - who has survived in the NFL on his versatility. Quessenberry is a better athlete though, and with some added muscle to go with continued technical improvement, he could be a nice depth-add in the middle rounds, with developmental upside of a starting tackle.
