We need to get over it. Darvish didn't want to come here for reasons we don't know. Yes, the Cubs gave him more $$$ and more years. Personally, I am glad the Twins didn't go that far out with big dollars to a good pitcher...but not a real ACE. There were other reasons, perhaps including the lack of a Japanese community in Minneapolis.
Would Darvish be better than whomever we have as our #5. Maybe...Probably. But who knows, the decline we saw in the World Series may accelerate this year. Or he may go on the DL next month and miss half the year. Personally, I am glad we didn't restrict future contracts to our young kids by giving him a sixth of the maximum budget we can expect...for the next 6 years.
As for performance by Duffey or anyone else, we'll know how they are doing in a couple months. May be Duffey, hell, Jorge may earn the 5th starter slot. Let's give all these young guys who were breaking in last year a chance to give'em hell this year. I love this team and I will still love them if we don't sign another player.
Darvish MIGHT be one of our 5 best starters? Might?
Ok. I think you might be too biased to even make your argument honestly.
