Of all the EDGE left, Sweat and Armstrong are most appealing. Not sure where the value pick is for them. At 4P15 if Crosby (OT/OG) or Settle or Hand (DE) is still around I'd imagine they go that direction based off the value of the pick. Still, 5p8 is a bit late to expect either Sweat or Armstrong to be around and I have to think that Fangio wants a young EDGE to work with.
I believe Houston is still available on the FA market. So Pace may have the option of kicking the Edge can down the road a year or two.
