I disagree about R Lopez, he will be a solid starter, but on Henson, here is what K Law says "Hansen still has a ways to go in terms of command, but he already has made substantial progress since the White Sox drafted him in the second round 15 months ago, enough that if we redid that 2016 draft he'd probably go among the top 10 picks."
So while the screw up on F Tatis hurts, Henson offsets that. You can't win them all.
