Keep in mind that this is dynasty because if this were redraft, it would not even be a question. Another owner will give me J. Charles, Donnie Avery and his 2013 2nd (2.2)....I give up Nick Foles, Alshon Jeffrey, Alex Green and my 2013 1st (1.11). 12 team league. I already have Foster, Ridley, Mathews, J. Dwyer, I am also deep at receiver. My big concern is QB depth for the future since I have Brady, Foles and Weeden. I am just very high on Foles, but I think if I added Charles to my roster I would be lethal, especially having him in the flex or as a matchup play.
Other factors, I am in first and will probably remain there and get a bye. The other trader is in the cellar and looking towards next season. Also, Ridley has some tough matchups in Week 15, 16 whereas Charles has some easy ones.
