The Pens may have the best 4th line in the league...the midget line may not score a lot, but they wear down D and keep the puck in the zone for whole shifts at times. Reminds me of the 3rd line of the past 2 seasons with Cooke, TK, and Staal. The positive is we took Cooke and put him in a more productive role and Staal will be as well, but we still have that killer 4th line.
