Moving Centers?

Now that the NHL season has wrapped up and the Los Angeles Kings have hoisted the Stanley Cup, the work begins for all 30 teams to do it all over again next season.  The NHL Draft is in 10 days and the free-agency period begins July 1.

However, there has been some rumbles about players getting moved, specifically some big name centers.  Joe Thornton, Tomas Plekanec, Ryan Kesler, and Jason Spezza are names getting mentioned in possible trade rumors, and throw in Brad Richards and what the Rangers will decide to do with him, and this offseason will be interesting.  Thornton has a no-movement clause that he can waive while Spezza has a limited no-trade clause, which means he has a list of 10 teams he does not want to be traded to.  Kesler was mentioned in trade rumors prior to the deadline last season, and he may very well still be moved.  Plekanec is a dark horse, as his name hasn't been mentioned as much, but the Canadiens would like to give the younger players more opportunities, which means Plekanec could be expendable.
