A guy I would love to snag in the late rounds is Andrew Copp, forward out of Michigan.
He's an overager, but he is so incredibly raw. He was an all-state HM QB for his high school football team, but lost his senior year to a broken collarbone. Played with the USNDTP (only home games) as a fourth liner/healthy scratch, so didn't garner much attention. Went to Michigan for hockey (lived in Ann Arbor his entire life), was a scratch for the first half of the season, then he scored 17 points in his last 20 games or something ridiculous. This was also on a defunct Michigan team.
He and Boo have good chemistry. He's a Callahan clone- he's a good skater, hits hard, hits often, extremely good defensively, is tough, has a knack for scoring dirty goals, and has great leadership abilities. Was voted an alternate captain of next year's Michigan team despite only really playing in the second half of the season last year as a freshman. Will be a sophomore Alternate Captain.
Has a ton of talent, and will be used in all roles next year at Michigan. Ideally could develop into that perfect 3rd/4th liner we are looking for (A la Nystrom, but much better).
He's better suited for wing, but as a small plus he's also pretty good in the circle, winning 54.5% of his FOs last year.
