Letang's not a guy you build a defense around, in my opinion. Too many holes in his game, and we have the pieces to make the post-Letang transition easy. He's not worth the money he's going to be getting, and Shero needs to trade him to get Sid's Neal, and to get out of that deal. It was a mistake to sign him to that deal, and he can bring back the pieces needed to really make this team a legit contender. Two very good reasons to send Letang packing.
We're a stronger team with a return like ROR/Eberle/Kane+allowing guys to move down and fill out the bottom-6+allowing younger defensemen to finally transition to the NHL than we are with Letang+Dupuis/Jokinen/Kobasew/Megna/Gibbons/etc in the top-6.
