Subban and Yannick Weber are 21 and 22, respectively, and both will be in the rotation next season. They have Josh Gorges and Ryan O'Byrne,who are 26 and 24, but yes, Hamrlik and Spacek definitely bring the average age of that corps through the roof. I think Markov is 31. It would have been nice to see the numbers he would have put up this season if he were healthy all year. I wouldn't be surprised if he were on the trading block.
I think that if he were, there would be a long line of suitors interested in his services.
As far as Giroux, the last thing they need is another small winger, to be quite honest with you.
