If you wanted to make this kind of deal, as a rebuilding team, you aim for 1st round pick or second, even by adding a 3rd or 4th from your own. There is absolute no point in trying to hit a homerun with 4-7th picks. Most of the time only top10 picks pan out as an impact player.
While they might not all be 'impact players' per say, there are still many players taken in the 4th round that becomes fine NHL regulars every year. Johnny Gaudreau, Alexei Zhamnov, Jere Lehtinen, Milan Hejduk, Viktor Arvidsson, Marc Savard, Eric Daze, Ryan Callahan, Mike Knuble, Sami Kapanen, Gustav Nyquist, Michal Handzus, Shawn Horcoff, Craig Smith, Vladimir Sobotka, Joonas Donskoi, Andreas Anthanasiou, Jean-Gabriel Pargeau, Eric Belanger, Casey Cizikas, Tobias Rieder, Ryan Malone, Matthew Barnaby, Alexei Ponikarovsky, Nikolay Borchevsky, Josh Anderson, Shawn Bates, Colton Sceviour, Tyler Kennedy, Jamal Mayers, Keith Yandle, Alexei Zhitnik, Igor Kravchuk, Lubomir Visnovsky, T.J. Brodie, Mathias Ekholm, Jacob Slavin, Sami Vatanen, Christian Ehrhoff, David Savard, Robert Svehla, Alec Martinez, Niklas Hjalmarsson, Michael Rozsival, Tom Gilbert, Toni Lydman, Joe Corvo, Jan Hedja, Barden Holtby, Philipp Grubauer, Jusso Saros...they all went in the 4th round.
You just gotta pick the right one.
Why not take a chance ? Any of those players I would pick ahead of Simon Bourque, wouldn't you agree ?
