System is stacked. I will include Tomas Jurco because he could end up in Grand Rapids to start the year where Riley Sheahan will not. I'll list about 5 players for each poll. It really is not obvious at all.
Mantha has the highest potential. I am of the belief that a goalie cannot be a #1 prospect for the main reason that they are way to hit or miss and they could have all the AHL success in the world but it may not translate to the NHL.
That being said Mantha with his size and offensive potential (a pretty rare combo). I really compare him to a young Dany Heatley with better skating but not as good of a shot.
I love, love, love what I have seen from Mrazek during his tenure here in Detroit. The poise he should in his very first game against a really good Blues team sold me on him. So close to a shutout in his debut too.... damn you Pietrangelo!!!
