First off, If Parsons or Fitzpatrick are there at 30, there is a pretty damn good chance they will be there at 31. They may even, and at least one likely WILL be there at 57. Trading for Anderson does NOT mean the Leafs are no longer allowed to draft a goalie this week-end.
Personally - I think the timing is perfect. Anderson is turning 27 in October - he's entering his prime. We will have a roster with a significant number of kids on it, and having competent goaltending means that every mistake they make will not show up on the scoreboard. I actually hope they keep Bernier until at least the Trade Deadline in order to shelter Sparks & Bibeau who are clearly not ready - nor should they be due to age & experience.
Anderson has had an above average save percentage at every level of professional hockey. He is a #1 goalie in the NHL right now. He will buy us the time to draft and develop his replacement - whomever that may be.
People are acting like we just traded for a 37 year old goalie.
As far as I can see, Bishop would cost a TONNE, and not necessarily be that much better. MAF is a non-starter. Elliot is too old. Other options like Subban & Kinkaid are completely unproven and too big of a risk.
Lou got the best available goalie at the best possible age for the rebuild. Solid goaltending is like having veterans in your lineup - necessary to avoiding Edmontonitis. The cost was in line if not better than what San Jose paid for Jones and Buffalo paid for Lehner. Anyone drafted at #30 would have been 4 years away from having an impact if at all.
