This does not stop teams like LA or Boston to go after players who hit say Bergeron or Doughty.
Sure. I suppose there are other examples too. The question is who wants that from hockey or from their favourite team. Of course it's good to try and protect your better players if it looks like the other is trying to hurt them. What Scuderi did though was just a normal hockey hit.
Cap hit aside, If they bought out Purcell the owner would still have to pay him. Now that's Edmontons problem.
Sure, but TSN tells that when Tampa traded Purcell for Gagner they didn't know yet that Coyotes were going to get Gagner off their hands. So instead of Purcell their owned would've had to pay for Gagner. The timing of these trades was right after the announcement of the new salary cap (which was lower than what was expected) so you'd think that cap hits are the reason behind these moves and not the actual salaries.
EDM's trade of Sam Gagner to TB for Ted Purcell doesn't necessarily mean Gagner will stay in TB. Buyout a possibility but so is a trade.
So why not buy out Purcell straight away instead of trading for Gagner? Tampa wasn't going to keep Gagner and even after trading him have to retain third of his salary. It seems that Yzerman took a complicated route just to get rid of Purcell. Purcell cap hit was lower than Gagner's so buying Purcell out would've saved them money.
