I'd stay far away from Virtanen.
It's one thing if a guy is struggling on a bad team and is in need of a change of scenery. It's another thing if the guy is putting up mediocre to bad numbers in the minor leagues too.
Virtanen was just a guy who got drafted way too high based on size. He won't be the last. I'd stay far away.
If you could buy low on Rick Nash and get him to agree to a Richards type deal, I'd be all over that. Otherwise I'd go hunting for BIG fish in the D trade market.
Campoli wasn't awful at all. He was pretty good, he just got torched on one turnover, got injured, and then was super vocal during the 2013 lockout which may or may not have got him blackballed (depending on who you ask). I'd have had him back in 2012 if he wasn't persona non grata. But they we traded for Oduya, so it worked out fine.
Speaking of, Oduya was an Olympian well before he suited up for the Blackhawks. He may have played his best hockey here, I'll admit I wasn't watching New Jersey very closely when he played there through his prime. He certainly played better with Hammer than he did with any of his partners on ATL/WPG but I don't think we can give Q credit for a reclamation project when the guy was already considered one of the best in the world by his own country's national program.
