That's questionable. Sure, Nylander is a better player overall, and better winger than Bozak is a C... but we have such a small sample size for Nylander at C, that it's hard to conclude that at this point. He could become better, he has that potential.
Nothing quantifiably better?

I'm not trying to make any case that Bozak is better... but you did say NOTHING quantifiably better than Nylander.
