Personally I think it's because the brain trust tries too hard to find a player with skills that matches up with what they perceive to be a team weakness...
Iirc, correct me if I'm wrong, one of the (but not the only) reasons for the Harry pick was he was supposed to be good at snagging the jump ball, potentially offering up a good red zone target... They missed on him because they overlooked all the other red flags because they were looking for that aspect of game play/situational football... They were myopic in their assessments, all the while overlooking the skill sets of available wrs who were better on a basic level...
And I will add, BB does not, or appears to not value the position to a high degree in general... Kinda treats it as a plug and play running back... To some extent it's true, but not so much when you want/need an elite pass catcher... Skill and drive matters at the wr position at an elite level much moreso than the RB position
