IDL FA Options - Harris, Casey, Atkins?

I think to really round out this roster a IDL who can push the pocket and offer a bit more talent than what we currently have at back up options would be ideal. Especially since we didn't draft any IDL.

Would any of these guys ring chase? I think we could get Jurrell Casey for sure coming off injury. Geno Atkins is one I'm unsure on.

Even a Beau Allen probably slightly outperformed Nacho when he was here and he is around. Another one of these guys might protect against a Suh or McLendon regression or upgrade Nacho/Khalil Davis.

Thoughts?
