As great as Casey has looked at times, I don’t see a way he doesn’t hit a wall and could benefit from some time down. He for sure looks dynamic offensively, but he’s also shooting at 75%. Him and Nemec have also gotten pinned in their own zone more than a handful of times.
Casey has looked better than Nemec, but Nemec deserves a little more benefit of the doubt. There is a good chance he started training camp less than 100%, and still might not be. That said, with the depth this team has, two guys need to come out when Luke and Pesce get back. Nemec and Casey are the obvious choices.
