I think you definitely made the right decision.
I really wanted to draft a RB early, but just didn't like my options when it got to me. Dropoff is pretty big once you get past the starters who get lots of touches, so getting an elite is really good I think.
Exactly, I was told to go for AB if i had the opportunity in the first round unless one of the top 3 RBs were available, but I felt if I didn't get a good RB for the 5th pick, then there might not be any RB talents remaining when my 20th pick came back around. I'm looking forward to seeing how my contest will play out between AK vs AB.
