Picking #9 is a complete crapshoot. Here are the last bunch of players picked at #9. A couple of stars, a few average players, and a bunch of garbage. If we have to give up a defenseman and #9 to move up to pick at #5, it might be very worth it. Players picked at #5 are almost always impact+ NHLers.
I couldn't care less about historic drafts. It is irrelevant to this one. Firstly, this draft is deeper than others, and secondly, I don't care what previous GMs have done in the 9 spot. In 2005, the Senators took Brian Lee, but just as easily could have taken Anze Kopitar who went 11th. In 2002, Florida takes Petr Taticek, but just as easily could have drafted Alexander Semin who went 13th. I could go on and on. On the flip side, The Sharks could have passed on Logan Couture with the 9th pick in 2007 and drafted Keaton Ellerby, who went 10th. Does that make the 9th spot less appealing?
