2.I'd assume most players are pretty dedicated, goalies more so than other positions given how precise they need to be. It's great that he's so dedicated but that doesn't mean he can sustain success. We've seen some pretty dedicated players over the years who once they hit that wall at 35 or so, there's a steady decline. This is my problem with getting a goalie of his age.
3.I'm not doubting his character but I think it's safe to say that this retirement deal was handed out with Luongo anticipating playing until about 40. I doubt he has any plans to retire earlier IMO. All speculation of course.
As has been pointed out, I doubt he or Schneider would he happy splitting time and with a top goalie prospect coming up sooner or later, somethings gotta give. A 33 year old Luongo is more valuable than a 35 or 36 year old Luongo.
