Argument against:
The argument against revolves heavily around money and taking reps away from younger players. Clowney might not be looking for a one-year deal and if he is, it would likely cost the buyer a large sum. If the Giants were willing to spend that type of money to at least complete and establish a sense of success in 2020, dishing out the cash might be worthwhile. However, Clowney would inadvertently be taking reps away from players like Oshane Ximines and Lorenzo Carter.
With Ximines having a successful rookie season, posting 4.5 sacks over 45% of defensive snaps, putting him in a rotational spot would only hurt his development. Clowney offers plenty of value and added production to the defense, but since the Giants are still in the middle of a rebuild, focusing on the younger players should be the priority.
