Yep having 2nd string edges like Barnett and Taylor bode well for a rested pass rushing group later in games so the sack numbers should go up.I don't get the lower projection for the defense: 19 Ints goes to 13.5, and 49 sacks goes to 42.8. One would think between the youth on the defense and another year in the system you'd expect those numbers to go up if anything.
The int rate definitely shouldn't go down because adding CGJ who's a playmaker should only make the defense better IMHO.
