Should I accept this trade in a dynasty FFL?

I believe that Thomas Jones will have a great season. 1500 yerds 12+ tds. All because hes running behind Alen Faneca, and Tody Richardson. Last year he did above average without them. This year, he ill do great with them. I have tried my damndest to get jones. i have him in 2 of my 3 leagues. he will be great this year.
