Interesting fantasy trade, Cano + Renteria for H Ramirez

[mbillie1]

Scoring cats are R, H, HR, RBI, SB, E, AVG, W, L, CG, SHO, SV, K, ERA, WHIP

Roster is currently

C - Russell Martin
1B - Adrian Gonzalez
2B - BJ Upton / Robinson Cano / Rickie Weeks
3B - Ryan Zimmerman
SS - Edgar Renteria (both Khalil Green and Alex Gonzalez are available on waivers)
OF - Carlos Beltran
OF - Alex Rios
OF - Magglio Ordonez
OF - Josh Willingham

I've been starting BJ Upton at 2B (Weeks I just now got off waivers) and while it's unlikely that he continues to tear it up, his numbers have been great. With Weeks and Upton at 2B I think that position is fine, so here are the two versions of the trade I have been offered:

Robinson Cano / Edgar Renteria for Hanley Ramirez
Robinson Cano / Josh Willingham for Hanley Ramirez

thoughts on this? Renteria's done fine but Ramirez is a stud, and I could use more SB anyway. I'm not worried about giving up Cano since I have 2 playable 2nd basemen. Give up Renteria or Willingham? OF is fairly deep on waivers and I've been playing him in the UTIL spot anyway.

FWIW 12 team league, H2H

Edit: where do you guys get your information? There are some extremely knowledgeable people here and I hear references to "such and such numbers" but I'm really just a TV baseball fan... where should I go looking for more, deeper info?
