Caufield is the same. His best attribute is his shot, and when he's not scoring, he's not doing anything to help the team, he's a burden.
It's tough for USA because they have two of those players in Kaliyev and Caufield. They can't be on the same line, especially when neither of them are producing at the moment. They can't play in the more gritty, defensive roles, because neither of them are capable of playing that game. So you have to split them up in the top 6 and just deal with whatever the outcome is. Luckily, Zegras is the best player in this tournament right now, and the Brink line is exceeding expectations.
