The easiest way to tell you who to use is for you to post a list of who is available, I am sure someone can point out a couple names for you.
The only other thing to go by is their stats and then check the names on depth charts.

If you guys can give me an example of a player from this list that is actually worth rostering, and more importantly why I'd appreciate it. But this feels like an assistant coach thread then, and that's not my intention.
I basically want to know how to scout DLs.
