Help WITH TRADE INVOLVING McCoy

[fantasy god101]

Ok Here is the deal I have Tim Hightower, who seems to be on the decline with beanie wells getting more and more carries, and Clinton Portis, who hasn't been spectacular this year and who i think may lose some of his value due to Ladell Betts going off the last 2 weeks.

If i am in a standard espn league and a guy has agreed to accept a trade of hightower and portis for 1 of the 2: Leshon McCoy or Hines Ward...should i do that?
and if so.. sould i pick up Chris Chambers or Jamaal Charles?

OR lastly, should i just forget about the trade all together and just drop hightower and pick up one of the above two?

I am in a 10 team standard Espn fantasy league (non ppr).

My Roster is
Aaron rodgers
Chris Johnson
Thomas Jones
Justin Forsett
Gregg Jennings
Brandon Marshall
Roddy White
Clinton Portis
Tim Hightower
DAllas Clark
Jerrico Cotchery
Mike Wallace
