I'm an Oiler fan who voted Jones, because I've liked him for a long time. I definitely think that Nurse deserves more credit than he's gotten in this thread. He wasn't just some fringe top line Dman. He was in the top tier.
Now, I would agree that Nurse has only been in that conversation for one season, and an odd shortened one at that. He was a top pairing guy the year before too though, although that was also a shortened, strange season. So yes, he's overpaid.
But, I have followed Nurse as well, and him getting to a top level was not a shock. He's gotten better every year. He's at an age where he is just entering his prime. If he were UFA, there would a much larger group of teams that would give him that contract than you people would think.
