Route Running - Appreciate his potential as a seam receiver to work vertically but he needs to play around contact more effectively. Rolls through breaks on steeper angles with effectiveness and like his ability to cut. He worked both from the slot, in-line and flexed wide as a pass catching target with intrigue.
Hands - His catch radius is monstrous and he has made a number of successful ball adjustments on throws that altered his hands and charged him with flashing outside the numbers. Showed good hand strength in contested situation to finish targets in traffic.
Versatility - Wouldn't peg him for a consistent role in-line because his frame is long and lean but he did secure some nice run fits on fold blocks. He doesn't have a lot of mass for a traditional role in tight spaces but could be bulked up if a team deems it necessary. Primarily a pass catcher.
Contested Catch Ability - Wingspan will provide wonders and he will make it difficult for defenders to play through his frame and disrupt his hands. He's got good high point ability on throws above the rim in tight windows when his passer can't drop on in over the top. Play strength and toughness isn't ideal.
RAC Ability - He's got plenty of juice, should be able to accelerate and run away from linebackers who draw him in man to man coverage. His creativity hasn't been given many chances to flash and he doesn't showcase a great deal of wiggle — instead he's a fairly upright runner when he's opened his strides.
Power at POA - Lacks the needed power in the lower half to uproot defenders in the box. He's more effective flexed wide and bullied safeties with his blocking assignments. Long way to go in order to anchor and hold ground in traditional in-line sets — team would be better off charging him with a more specific role in space.
Competitive Toughness - He's a fairly selfless player, as evidenced by his lack of receiving production. Never once saw lack of touches negatively impact his effort. Pure play strength isn't an asset and he's either going to need patience here to improve or be kept out of the box.
Flexibility - Shows good body control and contortion to adjust to throws as quarterback leads him away from defenders. His catch radius is boosted by torso mobility and skill to lengthen himself away from his frame. Could afford to keep his hips and pads lower all around.
Balance - Gets caught up with light contact too easily and will get knocked off his tracks in his routes. Will fall off of blocks despite foot mobility due to leaning too far over the top of his toes — needs to sit back on his heels, sink and play with a lower base of support in order to improve here.
Football IQ - Lots of games played — not a lot of volume his way. Simple improvements as a route runner should bring about more in the way of productivity and separation, especially attacking the middle of the field and uncovering in a timely manner to product chunk gains as a receiver.

Player Summary - Stephen Sullivan projects as a developmental receiving specialist at the NFL level. Sullivan has the athletic tools necessary to be an effective route runner and contested catch target — he possesses a massive wingspan to pluck throws up the seam. He'll need to be more savvy on his press and stem to avoid contact and play into space without having his timing disrupted; but it is easy to appreciate the upside he offers. Sullivan is a TE3 candidate early in his career but with room to grow.
