In short, I think you are overreacting a bit....your pitching is decent....and a preseason trade would hurt your hitting too much to make sense. Wait for the season to start, see how some of your high risk/high reward type guys are doing, and figure out exactly what your strengths and weaknesses are before worrying about a trade.
i agree that adding another arm would help. But while your pitching isn't a strength.....it isn't a weakness, either.
You ave a true fantasy ACE in Strasburg. Sale is a legit fantasy #2 Latos is a borderline #2/#3 Minor is a borderline #4/#5 Bailey and Estrada are solid fantasy #5 And Fiers is a good high upside guy.
It's not an emergency situation where you HAVE to add a pitcher now. You basically have an "average" starting rotation for a 10-team league.....which isn't a bad place to start the season at all.
And the problem I see with a trade right now is that you really don't have the necessary hitting depth on you bench where you can afford to trade away a top hitter. Eaton is hurt......Maybin is only good for stolen bases......and Morales is a huge question mark.
To get Yu, it would cost you at least Choo....and probably Butler or Gordon. And if you traded one of those guys away, you would have to count on Maybin or Morales as a starter, which i think would be bad news in a shallow 10-team league. Morales still has upside....but he has huge "bust" potential, too.
Yeah, your pitching would be better....but you would be taking a huge hit to your hitting......too big of a hit, in my opinion
You have more than enough pitching that you can be patient and wait until the season starts before deciding whether or not to make a trade.
You can see what, exactly, Fiers is going to provide for you. You can see how good Morales is. If Morales returns to the player he was before he broke his leg, you suddenly have the hitting depth needed for a trade.....but if Morales is a bust you wont find yourself having to start Maybin every day. And maybe you can pick up a big arm on the waiver wire.....there are always a couple of stud pitchers that come of of nowhere.
I think that you have a decent pitching staff. Everyone knows Strasburg is one of the best. I think Sale and Latos are solid #2 guys. Minor Bailey and Estrada and decent #4-5 guys and will provide a steady stream of K's while hopefully not killing your ERA. I just don't see a bat that you could give up that will allow you to improve your team with Darvish. I agree with the post above me and see how the first 3-4 weeks go before deciding whether or no to go looking for that big arm.
I honestly think you have a strong enough staff, so I wouldn't be trying real hard to make a move right now. If he offers you something you can't pass up then obviously take it, and it couldn't hurt to send him some offer where you are obviously getting the better end of the deal just to see if he bites.
