If Ridley makes the team in 2024, the second pick will be worth at least a fourth-rounder.

They are unable to move their 2024 second, third or fourth right now as they are potentially involved in this trade. Ridley is not under contract in 2024, so they are going to have to pay him or let him walk (and save the picks.) Saying they got him for a “fourth and fifth” is disingenuous.
