I get it. The known quantity, especially at a position of need, is appealing. But I also think your 4-7 prediction next year is pretty spot on, and I like our odds at that pick even better than I like our spot at 16, so I guess we're just coming from different foundations on this.
I'm one that believes in the importance of going hard after filling specific roster needs as long as it does not handicap you in another area. I've done pretty well in my fantasy keeper leagues in the past over paying to force specific deals when needed.
I value prospects highly, but I'm also lean heavily towards the now in what I want for my team. Sometimes that's a flaw, and I'm constantly walking the line of patience and jumping the gun because of it. Even with this strategy I usually was able to keep a fairly strong stable of young players.
I think that pick at #16 is probably 2-3 years out from filling a need. Which is also why I'd be willing trade it in a deal for someone like Skinner as well.
I do love the position we're in. They have options, but sitting on their hands would be a mistake IMO.
Edit: If it was up to me this off-season. The Avs would sign one of Hickey/CDH, one of Stastny/Tavares, and either trade up in the draft or trade for Skinner. Those would be my top goals, but the center would be a high priority. If I couldn't get one of Stastny/JT I'd look hard for a reasonable trade. Even without it though, a second line of Skinner, Jost, Zadina/Svetch would be a stark upgrade.
I'm a touch skeptical about Carlson personally as well.
