Shockingly the roster thread is arguing about Ghost, this time giving no credence to a nagging knee injury.
I'm sure the injuries have hurt his performance, given his production is more dependent on quickness and agility than most players, any lower body injury that saps those skills is going to hurt his performance. Dings will impact his play as well as major injuries (compare to Provorov who was one of our best players in the Pens PO series despite playing essentially with one arm, or Couts shining despite a bad knee).
The problem is that these injuries are becoming the "norm" for Ghost, and some of that may be due to his frame, he's just not very strong and he has been injury prone. And there's a lot of contact over an 82 game season.
These kind of players tend to have up and down careers, when healthy they can put together good seasons, intermixed with the "off" seasons.
So far, Ghost has had 2 good seasons in 4 1/2 years, he may finish strong this year, he may get dinged again.
It doesn't mean Ghost lacks value, rather, he should be viewed as a complementary piece, but not as a core player because you can't count on him staying healthy.
Which is why I totally agree with how AV has used him, keep the work load down and hope he stays healthy.
I think Niskanen has been overworked, given his age, but that reflects the limited options with Ghost dinged, Morin out, Sanheim and Myers inconsistent, and Hagg as your other option.
