Trade Proposal

[bondfast12]

So I got proposed a trade. I was wondering if you could let me know what you think. I'll post my entire roster just so you can get a better idea of what I got.
My Roster:
C - Miguel Montero 1B - Lance Berkman 2B - Jose Lopez 3B - Aramis Ramirez SS - Jimmy Rollins OF - Matt Kemp OF - Carl Crawford OF - Raul Ibanez UTIL - Jose Reyes UTIL - Hideki Matsui BN - Yadier Molina BN - Juan Rivera BN - J.D. Drew BN - Skip Schumaker BN - Garrett Jones
SP - Jon Lester SP - Jered Weaver RP - Mike Gonzalez RP - Jonathan Papelbon
SP - Ricky Nolasco SP - Jorge De La Rosa SP - Daisuke Matsuzaka SP/RP - Clayton Richard
The proposed trade is:
I receive:
OF - Adam Lind 1B - Miguel Cabrera SP - Edwin Jackson
I give up:
OF - Carl Crawford SS - Jose Reyes
What you think?
I'm giving up some big time speed and stolen bases, but gaining a better first basemen I think. I don't really know that much about this fantasy stuff though, first time doing this haha. I think maybe I'd rather have another RP instead of another SP too but I'm not sure. I'm also hesitant to give up 2 big names before the season starts.
Let me know what you think.
Thanks!

Oh, and my league is pretty standard. You go head to head against a guy each week. Get points for the standards: avg, hits, runs, rbis, steals, k's, whip, wins, era, and one more i cant think of right now?
