Tall, thin target with below-average play strength and separation ability, but very impressive ball skills to compete when it's in the air. Sills won't see as many free releases and easy long balls on the next level.

He should continue to improve but the transition to the pros could be challenging early on.
Possession receiver with impressive combination of size, speed and contested catch toughness.

He needs to play faster and sharpen his routes to become more than a traits-based backup.
