#1 Defenseman are incredibly difficult to find. The Hawks post-Chelios are a great example of this. Anyone remember Jon Klemm and Steve Poapst? Or if you want teams that weren't run by a cheap A Hole the Wings now without Lidstrom or the Flyers without Pronger. No matter how good the rest of your roster is, a lack of a #1 DMan can be really detrimental. Hawks are incredibly lucky to have not two #1 Defensemen right now.
Agreed, we just need to draft well, get a little lucky and like I said, make a huge trade. It is that important, as you said.
Look at D-men chosen in the top 5 the last 5 years:
2008
#2 Drew Doughty (legit No. 1)
#3 Zach Bogosian (solid 2nd pairing, still has upside)
#4 Alex Pietrangelo (legit No. 1)
#5 Luke Schenn (solid 2nd pairing, still has upside)
Probably ends up as 2 legit No. 1's, 2 good second pairing guys
2009
#2 Victor Hedman (good 2nd pairing, upside is top pairing guy)
#6 Oliver Ekman-Larsson (top pairing guy, likely to be legit No. 1 if not already, granted 6th overall but could have easily went top 5)
2010
#3 Erik Gudbranson (has struggled but still very young and has clear top pairing upside)
2011
#4 Adam Larsson (good 3rd pairing guy, has top pairing upside, will at the very least likely be a strong 2nd pairing guy)
2012
#2 Ryan Murray
#4 Griffin Reinhart
#5 Morgan Rielly
Way too early to tell.
I think it would be a good idea for the Hawks to do this in a couple years. They need to identify a player or two they really like and go after him. For me, if I was to do it this year, it would be Ristolainen, and he probably won't even go top 5. Not that I'd mind Jones, who wouldn't, but we probably aren't getting into the top 2 this year. What I like about Ristolainen on the Hawks is, let's say he doesn't reach full potential, he is so big and physical that he could be a great asset on any of the 3 pairings.
