I only take two RBs in the first 5 picks and I'm really lacking depth at that position.
Don't get me wrong, though. This is still a very good team. I have amazing depth at WR and I have an elite TE (Kittle) and QB (Luck). However, outside of my two top RBs (Johnson and Montgomery) I have very little depth and spent a ton of late round picks on flyers that may or may not work out.
I would have much rather had at least one more RB in the first 5 rounds to give that position some depth.
You need to focus on RBs early because every startable RB is pretty much gone by pick #60.
