Yea Teams are running to get rid of their #1 Centers for lesser centers.
Ryan O'Reilly, Jason Spezza, Joe Thornton, Tyler Seguin, Jeff Carter, Eric Staal, Ryan Johansen, Ryan Kesler, Brad Richards, Derek Stepan, Vincent Lecavalier, Paul Stastny are some of the high profile centers that became available in the last few years...
As for making a package, Sens could package Turris, a 1st and a prospect to get a good upgrade. The quality of the prospect would rise depending on the quality of the center acquired. If a team was luckily looking to do something like this, then it could happen.
