It's not too often that an NHL record that's stood for over one hundred years gets broken.  That happened on Wednesday night.  Despite his role shrinking, Kris Letang had the period of a lifetime.  Letang dished five assists in the second period in a seven minute span, becoming the first defenseman in NHL history to record five assists in a period.  He finished the game with six assists, all at even strength to give him a +6 rating in the 7-0 win over the Islanders.  Even with this game, Letang is far from the defenseman he used to be, partially due to age, and partially due to the arrival of Karlsson.  He's under two shots per game, and has only three goals as a result.  However, the assists are still very good, the hits and blocks are solid, and the PIM are much higher than they've been.  He's the perfect #3/4 defenseman on most teams since he's hitting most of the categories and piling up assists.
