Hold on. So, if Greinke is a FA we can try to sign him but if we trade for 2 years of control then we can't try to sign him? Okay.
Huh? I'm just saying I think it's insane to cripple our club, and trade Zimmermann, who we still have far more than two years of control, along with Desmond and a third, for two years of Greinke. I'm not a fan of trading for one or two years and losing young talent you still have several years combined control over. Get a FA pitcher, don't lose a ton of talent you still have years of control over for two years on one player. Nine times out of ten, that's not a move I am in favor of regardless of who you are trading for. Likewise, I accept I am in the minority and most fans and GMs often believe it's worthwhile depending on the situation.
So long as there is an equivalent FA option available, I'd rather pay much more money for them than lose young prospects already in the majors for a couple years of a player. Zimmermann could come close to Greinke's level of success in another year or two. Losing him and two other potentially excellent players for two years of Greinke, or Garza, or another ace, just isn't worth it for me. Again, I realize most don't agree with that logic.
