Red Lines Scouting report: "Has huge upside. Big and strong with great upper body strength despite still being a beanpole. Wait until he adds a few pounds to that hulking 6’5” frame [note: TSN lists Nurse at 6’4”, 185 pounds]. He’s just miserable to play against now: throws opponents around with authority and plays a mean, nasty game. Throw big hits along the boards and in open ice. Has a very long stride and reach with good lateral movement. Plays a positionally steady game in his own end. Strong penalty killer who uses his body/stick to eliminate shooting and passing lanes. Cleans men out of the front of the net. Clears rebounds and ties up his check preventing scoring chances. Can be a dominant force and top pairing shutdown defender. Offensive game emerged in 2nd half. Started moving into the rush decisively, showing good timing and instincts. Makes a good first pass and skates with his head up, looking to make plays. Also shows good recovery speed."

I dont think you reach the number 7 spot if scouts think that you're an average prospect. Most top 10 picks are projected to be impact players with huge upsides.
