Well I think that expectations are too high if that would not be good enough.
Here are some odds to consider for historic RB performance.
Hunt was the 6th RB selected in 2017 so he has a 60% chance of providing more than zero career VBD and 129 over the course of the players career, hopefully has one season where you are getting 32 or more VBD which should at least be enough of an advantage to help you win some head to head match ups. Otherwise marginal compiling of VBD over a career ( a little each season) isn't really going to help you win.
So that is a 60% chance to not be worth nothing.
As the 6th selected RB Hunt has a 20% chance of having a career over 200 VBD. 200 VBD would be a pretty exceptional career where the player should finish top 12 at their position once, or possibly three RB two type seasons during their career. The more of this value that occurs in one season the better, that is what helps you win games.
The 6th RB has a 10% chance of a 400 VBD career which is a performance level that only the elite players in FF ever achieve. 200 career VBD is a really high bar as well. 400 career VBD is like LT or Faulk level careers, not many of those.
So if are you saying that the 12th pick has a good chance of having a 200 VBD career I would say the history disagrees with that expectation.
Here is the historical VBD generated by draft pick. You will see that pick 1.12 and pick 2.01 are worth approximately 150 career VBD which is below the 200 VBD threshold of a 'long term successful fantasy career;
To put this another way, in a typical league starting requirement of 1QB/2RB/3WR/1TE there are only 84 players who will have positive VBD for any given season, call that 96 players if you have a flex option/ So anything lower than player 96 does not provide you any value in terms of VBD or if they do, it would only be for a few games.
So according to this pick 100 is about the same as pick 1.12 which is below the 200 career VBD threshold.
You should be hoping that the player can provide you even one good fantasy season, as most of them are not going to, and especially not from this late of a pick on average.
Of course you can always pick the right player that late and get lucky, but the odds are very much against it,
