Yeah agreed, I was obviously first overall pick so at 20, 21 I was planning on going RB, WR but when I saw Thomas and Marshall there I had to pull the trigger. Miller could be a dark horse this year, but as you said my WR depth could work to trade for a solid RB2 if he's not.
Also, I like my handcuff of Ray Rice and S. Jax. If something happens to either one, Pierce or Rodgers could serve as a solid RB2.
