I love a ton of guys in Colorado. What's realistically acquirable is a different story.
If they are going to end up moving O'Reilly I'd pay a hefty price to get in on that. The backhand goal he scored tonight was a beauty. He's a great player. Very unlikely he's available or we'd be in on a move of that magnitude. Likewise, if they're going to keep O'Reilly they may consider moving Stastny, who is a upcoming UFA. I would love to be in on that as well, but it's probably best not to move assets for a guy you may have a chance at for free. He's like a more talented Stepan. Very similar game. In fact, I may not be able to think of a better comparison. They would make a great one-two punch. Again, it's doubtful we're in on something of that magnitude right now.
What's realistic? Barrie is the obvious target. Colorado is doing great and could use some more established D. Del Zotto and Barrie are nearly mirror images. Barrie is one year younger, has less NHL experience (DZ began his career quite young) and plays a similar game. He's prone to similar mistakes but has less experience and they're not as glaring/look more correctable. Him being a righty makes him a very sensible choice for us. I think DZ for Barrie is a low cost/high reward type of gamble for both teams. If all goes well, both guys should be 40pt #4 dmen. It just makes too much sense.
What else is realistic? McGinn would be a great addition for us. He has more scoring touch than he's given credit for. Colorado's offense is deep so he doesn't get a ton of top six time, but occasionally he does and on those instances he produces fairly consistently. I've watched a lot of Avs games the last couple years and he also hits an obscene amount of posts. He's very physical and he's got serious wheels. He's like a tougher Hagelin. I like him a lot.
I also think it would be a good move to look into bringing Mitchell back. He's really kind of found/solidified his game as an excellent bottom six center. He can play third line, no problem. Far more effectively than Moore/Boyle but can also be a great fourth line C and PK guy. He's turned into quite a warrior as well, playing through pain and stitches a lot. Another low cost/high reward kind of guy. He could be a real solidifying force at a low cost. He's certainly a better option than most of our bottom six guys of his ilk.
