Your 1st line will get pushed out to the blue line by any team with defensive size. It'll be like picking cherries for their goalie.
Your 2nd line is not much bigger. Given the trend of defensive size for physical d-men you're giving it up as Karlsson doesn't play a physical game (he gets hurt when he does), Deangelo is more skill than size, and Burns is approaching 80 (given his wear). Karlsson and Burns on the same team was tried before--it doesn't end up well.
