If you need goaltending that's not a problem for me. Wheeler is a stud but Mrazek is a Vezina dark horse, Carlson is a stud on the blueline they're more than enough of a return for Wheeler, throw in the better picks and you dominate that deal. Polak despite hits being a category is replaceable on so many levels there are definitely better options available.
I'll take the two players who are top 10 at their positions and the better picks.
