Good post. Which is why for me I don't get invested that much on who they pick in day 3. The draft is a crapshoot, it becomes even longer odds as the days go from Thursday to Saturday. Feel like the top of the 4th is when teams can regroup and take those guys who someone slipped from should of been day 2 guys. 6th and 7th round picks are just securing priority free agents.
Ideally, day 1 pick is a starter/building block. Booker fits that.
Day 2 should also have starters, but may be a year of development. EZ and Revel fit that.
Day 3 to me, is the traits, potential, guys with flaws you hope with a prayer they can overcome type of picks that can be solid depth, role players or possibly diamond in the rough starter. Very rarely will you get a legit starter.
With running backs, I feel like one of Blue and/or Mafah, can provide solid play. Replaceable? Sure, but Blue has speed so he could be a good change of pace back. To be determined how Mafah can turnout, but worthy of a hail marry pick
