Seider can also play on his weak side really well, so we could in theory end up with a top pair of Seider and Drysdale. Might even be better for him since he's better defensively and he can keep his stick in the center of the ice to break up plays, and it gives him a good shot from the point too. I think Drysdale can play weak side too. That being said, I think Sanderson is better in almost every way aside from skating. I think he would have shown that in the playoffs had they happened.
I'm more in line with taking Raymond or Perfetti, but I'd still be happy as hell taking one of the two D-men there too. I think when the worst prospect in the top 10 is Anton Lundell, who is still fantastic, you really can't go wrong.
