https://www.si.com/nfl/dolphins/news/miami-dolphins-noah-igbinoghene-kelvin-joseph Don‘t know anything about Kelvin Joseph. If this article is right he seems to be a good special teamer.
Nope - if they took a flier on him in the fourth round or later, it wouldn’t be much of a problem. No one on earth had him going in the first round. There’s no guarantee that Grier would have hit on whomever else he took there, but I think the odds are pretty good that they would have been more productive than Noah I.
Too new to the position to warrant a first round pick. And bringing in a developmental player to play defense for the notoriously impatient Flo was only going to end poorly for Noah. There was no chance that Noah was going to be on the field enough to learn from mistakes. We made a great trade with the Packers and then lost the trade. One of the most Dolphinny draft decisions ever.
