Not a big fan of CBS site, but their writeup on Spruce is on-point. Hope he is ready for special teams, because he's gonna have to excel there. But here again we see a guy with route running and insane hands, and I'm diggin the theme by Snead this year.

STRENGTHS: Spruce is a polished, dependable route-runner with the soft hands to quickly become a quarterback's favorite target. He uses deceptive quickness off of the ball to escape press coverage and incorporates body lean, varied gaits and an occasional push-off to gain separation from more athletic pass defenders. He has a lanky, athletic frame and possesses terrific ballskills, including the body control and catch radius to pull in passes far outside of his frame.
Spruce has good hand-eye coordination and soft mitts to pluck the football and secure it quickly. Effectively uses a jab-step to force opponents to commit to one direction before turning the other way, scrambling for extra yardage. He shows good vision to set up blocks and isn't afraid to turn things upfield into traffic rather than attempting to circle around defenders.
Spruce shows vision and toughness in working across the middle on drag routes, slipping through traffic and showing the focus and toughness to pull in passes with defenders closing in.
WEAKNESSES: While his production is undeniable, Spruce does not possess ideal athletic traits. Has just average straight-line speed and relies on sharp route-running (rather than true explosiveness) to generate separation. He'll struggle to get free against NFL cornerbacks on the perimeter and doesn't possess the size, leaping ability or strength to consistently win 50-50 balls.
IN OUR VIEW: Spruce is a classic possession receiver who wins with savvy route-running and soft hands. He production will get him a shot but he's not surefire NFL prospect his numbers would indicate.
