He's a bottom of the lineup rental player who's been on the team for literally a week and a half. I get being annoyed in the moment but whining about it for pages and pages and openly wishing for the Oilers franchise to crumble because of it...yeesh. I'd understand and join in if it was Thornton or Vlasic or Hertl or Pavelski who got sucker punched but Polak? Who cares?
So you do not care that the depth the sharks added could potentially be hurt and will hurt the sharks if he is out long time. Even being a bittom pairing player he is important to the team.
