2 to 3 mins more a night, adds up over a 82 game season, and for a young defenseman like Josh, have the assignment of handling the league's best lineups, night in and night out, has an effect on him over the course of a season.
We need Josh playing defense first, ensuring he develops fully into one of the best defenders in the league. Once he has mastered that, you can slowly start integrating him in to the PP, which I fully expect to see this season.
Issue with Trouba? How so? He was offered a sizable contract by most accounts, one that would reflect a number one Dman, he turned it down for reason many believe have nothing to do with usage.
Bottom line it Josh is getting 1st pairing minutes, against first lines, other teams best, night in and night out. His primary focus is to play D, not to score PP points. The fact that we had a top PP across the league tells us we do not need Josh's offense on the PP anytime soon. We are doing just fine there.
With that said, I am sure Maurice feels he can handle some xtended duties and I fully believe we will see him get some time on that second unit.
