Quoting: danni04
Koivu for ROR alone is a bad trade for BUF, agreed. I probably failed to stress that the main value for BUF from the trade is Spurgeon (as a compatriot for Dahlin as you pointed out). But because ROR for Spurgeon is still an uneven trade, MIN adds Koivu to 1) close the value gap, 2) give BUF a player, who doesn't have qualities of ROR, but can play 2nd C behind Eichel (he still notched 45 points last year, that's only 15 less that ROR and there's still the Spurgeon factor). 3) relief a bit of cap-space to afford this.
As I mentioned in one of the previous replies, if BUF still doesn't like the value, they can probably keep McCabe and/or MIN can throw in draft pick/A Stalock/J Greenway/other minor assets to close the gap. The other option is to swap Spurgeon for Dumba, but that seems like a bit of overpay from MIN's side to me.
Greenway is not a minor asset.
Koivu had less points on a much higher scoring team and had either Granny and/or Zucker on his wings almost all season. Remember Foligno was a middle-6 player in Buf, and he was a potential scratch here in MN. That's the gap in FWD ability between the teams. Put ROR in Koivu's spot last season and he's challenging Staal for the team lead in points, and finishes top-3 for Selkie.
Koivu and Spurgeon aren't the missing peices for Buffalo to become a Cup contender, they probably wouldn't even make them a fringe WC team next year. They only have 2 years of service on their contracts and then Koivu retires and Spurgeon can walk after the season (assuming Buffalo is is in contention for the Playoffs and doesn't trade either of them at the TDL).
Brodin, Dumba, Granny, Nino, or Zucker would be the players Buffalo should be the main asking for as a return for ROR, they fit better for age, term, or ability. Spurgeon (and Coyle) would be an add on player, not the main piece. Everyone else, besides the ELC players, is just unneeded stuff for Buffalo.
Spurgeon and Koivu could be the missing pieces for a few other teams, but those teams are already Playoff teams. Not teams coming out of a rebuild and might make the Playoffs in the next 2 seasons.
