Who wouldn't get frustrated when GMGM and coaches hooked him up with only no-talent centers like Laich, Perroult (I like MP but he's not Backstrom)... You would loose the excitement of playing when only playing with these type of players who don't have the skills Semin has. 
Sorry, but you have to be smoking something expired if you think Laich isn't talented. He is the core of that team. Ask the players. Just because you don't see him scoring every night does not mean he's not one of the most productive players. I'm not sure what you're watching, but Laich is one of the hardest working hockey players in the NHL. And probably the hardest working one on the Washington Capitals. He's been running the drills and leading practices for years already.
Not only that but he's able to play center, wing and
defense. Yeah...he's worthless alright

I was a big fan of Semin because of his mad skills. I was not a fan of his complacency and lack of consistency. I really dislike him because he put the Caps in this situation. They were one game from being in the Stanley Cup finals and yet the Caps felt it was better to let someone with his skills go. We can argue whether the Caps should have let him walk without replacing him with a top notch free agent. But if he had played with more desire and heart we wouldn't need that debate, he would still be here with a longer term deal. That is on him. I will never forgive him for that.
I agree Semin has dug his own grave. He has tremendous talent and potential, but he lacks heart and determination. If he played to his potential he would have a 10 year contract.
