40 sacks should be the minimum you want. 50 or more is the goal
Here's the minimum we should expect
OLB 20
DL 10
ILB 8
DB 5
Total 43
Here were the sacks last year
OLB 19 - Worilds 7.5, Harrison 5.5, Moats 4, Jarvis 2
DL 11 - Heyward 7.5, Keisel 1, McLendon 1, Tuitt 1, Cam Thomas .5
ILB 3 - Timmons 2, Spence 1,
DB 0
Total 33
You see that last year the OLB barely did enough and the DL did a nice job. The ILB and DBs couldn't blitz much because the coverage was so bad.
They have to get 20 sacks from the OLBs. Harrison and Moats should be able to combine for 10. That leaves Jarvis and Dupree. How much does Dupree need to contribute? If Jarvis plays like a 1st rounder and gets 8-10 sacks, then Dupree doesn't have to do much. But if Jarvis stays at 5 sacks or less than we need Dupree to have a big rookie year.
So yes, Dupree needs to make an impact, unless Tuitt steps up and the combo of Tuitt and Heyward can get 15 sacks.
If the secondary is better, then that will allow some more blitzes from Timmons and Shazier. Timmons has had 7 sacks in a season before. He can have 4 sacks easily. Shazier is an athlete they haven't had at ILB since Chad Brown. 4 sacks is not impossible for him either. That give you 8 right there.
Add in a few random DB sacks on blitzes and there are your 40 sacks. It can be 50 if an OLB has an unexpected 10 sack season.
