So in other words, Romanov is more physical, and more engaged in the D zone because of it. That's basically what I said.
They are similar in terms of upside. Both mobile, undersized D (Mete much more so) with limited offensive potential, despite being successful offensively in juniors (Mete more so). Romanov has more potential defensively, but not anything special. They had similar rookie seasons with the Habs. We'll see how it goes, but I don't think Romanov is sure fire top-4 D like some here would have you believe.
