Just posted the same thing about the linebackers right before I read your post.Agreed... neither Tart, nor Jones is gonna give us much pass rush. These guys are there to soak up the double teams.
I've said this several times, I REALLY like both players. They won't generate stats, but they will just completely clog up the middle of the field and let our more athletic players clean up.
Our LBs are going to love these guys.
