Too me at least Klingberg was fairly invisible against the Avs, I don't think he did too much good or too much bad (he lost a battle on the Avs 4th goal, but Spezza deserves the lionshare of the blame there for completely blowing his assignment). He spent the majority of his minutes matched up against Crosby in our prior game and according to LatvianTwist, that was the first time in 9 years that Crosby has been held without a shot on net, so I think he did something right.
Sharp looks as fast as ever and his shot looks as powerful as ever, he got off a couple really dangerous howitzers down near the half boards that were just slightly off target. I only watched 1 pre-season game, that being the Blackhawks game, I thought he was the Stars best skater in that contest (or neck and neck with Seguin at least). So far, he has been held off the score sheet, but he did record 3 shots on net against both the Avs and the Pens. I'm betting it's just a matter of time till he starts lighting the lamp.
