There's no "I" in "win"
I see a lot fo you gusy counting Hudson as part of the trade for AZ. I don't agree w/ that. I could see it if they dealt him right away, but they held onto him for a half season. That trade w/ CHI is totally separate from this IMO.
NY gets: Granderson (Give up: Kennedy, Coke, Jackson)
AZ gets: Edwin Jackson, Ian Kennedy (Give up: Shlereth, Sherzer)
DET gets: Max Sherzer, Austin Jackson, Phil Coke, Daniel Shlereth (Give up Granderson, Jackson)
I think that is the trade we need to evaluate. AZ really helped themselves by getting Hudson, but again, that was over 6 months after this trade. That wasn't at all a factor in their decision making for this trade. They thought they were getting a great pitcher in Jackson based off of a fluke season in DET.
I think we need to see 2 things before we can for sure say who won... 1.) How does Granderson hold up vs lefties? He had a 902 OPS vs righties this year, which is right in line w/ his career norms. Him mashing vs lefties is what let him make the jump from good player to elite player. I need to see more of that before I crown him. 2.) Ian Kennedy is pitching way better than he was ever projected to. I want to see some more before I say that this is what he really is - an ace.
Bottom line is, there is NO CLEAR WINNER IN A TRADE, UNTIL ENOUGH TIME HAS PASSED TO DETERMINE SO. Sort of like, there is no clear division winner until 162 games have been played (cough, red sox, cough)
And just to play devils advocate, I bet you anything the Yankees would be a much stronger team with Jackson and Kennedy right now, than with just granderson. They already have an elite offense, and if you haven't noticed, the Yankees rotation is not good. If you haven't tuned in yet, they threw Freddy Garcia on the mound today. Yes, Freddy Garcia. So I'm pretty sure Jackson + Kennedy> Granderson for a team with questionable pitching options. Because you still have jeter, cano, tex, arod, swisher, etc.
