Are people down on Kass?
If so, it's because you expected too much. I really like him in a bottom six role. He seems to mesh well with the team too, that was my biggest concern.
He scored at a 15-20 goal, and ~30 point pace in each of his two seasons before coming here. He was playing ~12.5 minutes a night in those two years just like he has been this year.
I was expecting more offense from him than he's shown. This year he's producing at a ~8 goal sub 20 point pace. He's demonstrated he's capable of more playing similar number of minutes with similar quality of linemates. Not sure why a bit more offense should be beyond reasonable expectations.
Don't get me wrong, he hasn't been terrible. He just doesn't really do much other than run around, take penalties and get in the odd scrum after a whistle. Not sure the nearly 2 million it would cost to qualify him is worth it.
Funny, the only reason I do think you bring him back is if you think you can expect more for him. Because if all you're expecting is this, he's just not worth the contract.
