Depends on if they want to sign the 15th guy or the 10th guy. Rough estimation is that using the BAE will be about $5M more expensive than filling the roster with NWG. Given that they spent $3.5 M for Hughes, I'm guessing that the money isn't a problem here. It'll probably come down to how much they believe in Oni/Hughes. But I'm with you, I would definitely look to add a perimeter defender. Dunn (who is a PG but can defend anyone) and Harrison would be at the top of my list.
Really should not have drafted Doke and gone with Bane/Bey/Woodard instead.
