Because if the Pens let him go he becomes a free agent which means you won't be the only team trying to sign him.
Right, which is why I think a trade after the season is more likely than a straight up buyout. Someone will throw Pittsburgh a third or a fourth round pick and a mid-level prospect for him following the season and we will take it.
It's not going to happen this week though. There's just no incentive for anyone to act here.
