In my 12 person 8 keeper dynasty *points* league I give up:

Chris Davis
Joc Pederson
Taijuan Waker
9th (1st round) pick

I get:

Mike Trout
Brandon Moss
11th (3rd round) pick

My other outfielders are Springer, Harper, Pollock, Blackmon. I have no other 1Bs

I don't think so... While I love Trout, you giving up a heck of a lot for your future. Davis is still an excellent player currently (obviously, not the best player in baseball like Trout, but still good), but you'd also give up a potential ace in Walker (and he's looked like one in Spring) and Pederson, who is a potentially excellent future ball player. On top of that, your first round pick... Although it's tempting, you gotta pass.
