There is a big reason for this and it's very simple. Mittelstadt and Olofsson have been out with the 3rd pair D guys more than the top four guys.He's played with two of Jost, Girgs, Okposo, Asplund, Mitts and Olo about 92% of the time. He's been unsuccessful when put with those players, most of which are garbage, replacement level players. While you're right, it's a small sample size, I think it's important to note he was dominant when coupled with better wingers. -Agree to disagree on Mitts, while it's not a great stat, there's a reason he's the lowest +/- of the forward group.
