I don't understand why this thread needs to be bumped continually.
Donato is a good young prospect who was not ready to play in the top 6 on a contending team and not good enough to keep the 3rd line afloat on his own. He really wasn't remotely close to being ready for either role. The Bruins are pretty set on NHL left handed wings with Marchand, DeBrusk, and Heinen. And in the prospect pool, Bjork does everything better than Donato but shoot. Bruins dealt from an area of strength. The Bruins badly needed someone who could solidify the third line. Coyle can do that. Especially when Pasta, Heinen or Mojo get bumped down to help him out when Pasta comes back.
That doesn't mean Donato won't develop into a nice offensive top 6 winger. He needs to work on his skating and his strength. Everything else is there. He can put up points on a bad team today right now. But, he is still a couple years away from being able to be that guy on a good team. Or maybe he doesn't improve. I would bet a lot on Donato improving.
I think it ends up being a win win trade. I get that some Minnesota fans need to come out and say "they won the trade" because they were on the short end of the stick on some of these other trades. But the Wild didn't win the trade. Both teams are happy with the trade. Thats a good trade.
