The Cubs aren't winning the World Series this year. Im not dumping the farm for a rental. The Cubs aren't going to go for it like the A's last year. Their trades will be thought out for future not present. This team is not one of the top teams. No one is saying they won't do some trades, but they aren't going to sacrifice years for one year.
I don't think you have to sacrifice much of anything. The A's are going to trade Kazmir. I mean, why would they hold him?
You don't get too many chances to make runs at a playoff spot, and you need to take advantage of it whether you make it as a WC team, or search for a division title.
You can point to next year as the most realistic chance, but they could be bitten by the injury bug (because it does happen) and not have this chance again until the following year. I am not saying to push the panic button.
I am merely saying to take the opportunity if it presents itself.
I would rather take a chance with a starter and some bullpen help then I would a LF'er at this point, because I think the Cubs have a fair amount now internally, and/or when LaStella and Baez come back, this would open up some opportunities and strengthen the bench as well.
The Cubs could probably get Kazmir him for Billy McKinney or thereabouts, and pick up the rest of his contract.
All of a sudden, a rotation of Lester, Arrieta, Kazmir, Hammel and Hendricks is a lot more palatable. What it also does is increases the chances to go on sustained runs in winning, OR, stops losing streaks when you throw better pitching out there.
Riddle me this? Would you rather lose someone like McKinney (who in all likelihood is blocked) and throw Kazmir into the rotation, put Wada as your pitching depth, or remain status quo?
I know which direction I am going.
edit: This of course is only my opinion if the Cubs are staying in contention.
