When you draft center , you don't know if he is, THE ONE, your number one c enter, but if he is you don't trade him.
Circumstances can change, a player might want to leave or a player's team started a rebuild or a player's team is in the cap crunch. In all of those case's teams want prospects and picks, when the time is right Red Wings will have both, surplus prospects and picks to trade for.

Dalibor Dvorsky is in Slovakia's U18 WJC team, he is number 1 in my scouting list. I like his defensive game, it's already in very good level but im not completely sold on his offensive side yet. But he does sound like a complete package, something what Yzerman is usually very interested in. Skating has been said as his biggest weakness but it's not a deal braker, skating can be develop with the right coach.
"The Slovak centre has the size, strength, skill and competitiveness to project as a solid two-way No. 2 NHL centre, equally adept at scoring goals and making plays." - Bob Mckenzie
Sounds familiar.... sounds very much what the organization values on a player.
