Pretty easy yeses to all

Trades are fine.
Still need goaltending fixed.
Wild still have too many wings.
I'm assuming you weren't worried about the lines.

Brodin gets you essentially a middle six player but Dumba gets you one of the biggest trade packages in recent years with 2 established NHLers under team control and essentially 2 first rounders.

Brodin and Dumbas value are not that far apart Dumba has an extra year but brodin has a lower cap hit so they shouldn't be that far apart.

If your looking at trading Dumba the package St. Louis paid for Faulk should be the model.

What would the price be for Foligno?

My price is a 2020 2nd and a 2021 4th

Bos declines the Foligno trade.
1) They NEED a 2nd-line-RW SCORER like Palmeri/Reinhart/Tuch/Atkinson/Tyler J etc.
2) That US$2.875M for M.F., likely to be in a bottom 6-roll w/ BOS, would take away from the pool-of-dough$ needed for key re-signings in Krug, DeBrusk and Grizz.
