I remembered reading that Brown wasn't having surgery either or that surgery wasn't going to be required.
If someone can update this it would be good.
Still, if Ben Bishop, a player that has nowhere near the same amount of experience or NHL success that Bernier does got Cory Conacher, a Calder candidate who finished 3rd in points among rookies and was 1st in plus/minus of the top 3 Calder finalists and a 4rth round pick (which is a high 4rth) then Bernier should be able to return more.
So while I like Frattin and would happy if he were part of a return the fact that he has had his share of injuries has to have some sort of impact on his overall value at least in this deal and why I see a return closer to this years 1st and Biggs or Frattin and a 2nd plus a 4th being more fair.
That said, I don't see the Leafs ending up with Bernier.
