dude, no way i would make this trade. Charles is hurt for at least 2 weeks. your only getting 2 players for 1 with this trade here. Torre Smith and Percy Harvin is good in PPR and Special team leagues only. A.J. Green and Wes Welker are studs in non PPRand Non spcial team leagues.
keep your players dude. pick up Marcel Reece if he is available or Vick Ballard/ Chris Ivory.
