No. As far as needing more in the RB dept, I agree; BUT, not with a trade for Ray Rice. Hold onto Thomas, he's a 1st round pick in drafts this yr & has CAN'T CUT status.. Ray Rice is not going to reverse your fortunes at RB.. Package Jennings/Colston/Cooper for a solid bell cow like a Leveon Bell or Zac Stacy or for both (Vereen&Gerhart).
Good Luck!
Yes, you lose on D.Thomas, but Fitz isn't bad and you need another back.
