Our Pass rush is non-existent IMO because we are now trying to rush the QB with 4 defensive linemen INSTEAD of our historic 5 defensive linemen.
ALL of our past accolades in sacks/hits have been with 5 rushers...period. Now, we are trying to have the same production with 4 players WITHOUT having a true 4-3 DE on the roster.
We need a big, strong pocket pushing DE/OLB on the offenses right to make a 4-man line work. Dupree is a hopeful replacement as he is over 260# and can move but now we are playing guys over there who are more of the 'edge' style rushers. This will never work as we are giving up the QBs primary line of sight by not 'pushing' the pocket closed on this side.
Lamar Woodley was exactly the type of 'thick-built' player you need on that side of the defensive line to push the pocket closed. He NEVER was an 'edge' guy who bent his way around the end but more likely pushed his way into the backfield. (even then, he had an extra DL to make sure HE had to be single blocked)
Until we can get Dupree back on the field (and he still may not have the power to push the pocket) I would go with Tuitt at DE with Hargrave/McCullers at DT along with Heyward leaving Deebo at RDE.
Hey, IF we are going with a 4-man front, why should we be playing with undersized players in that front? All we will do is wear them out and break them down. Most ALL 4-fronts have 2 players over 300# playing inside and 2 more over 270 on the outside!
When we were successful in the past (on passing downs - Nickel defense) we had Keisel and Smith as DEs/DTs on the field with 2 OLBs over 260#. Woodley was playing at 280# and we all know Deebo has been over 260# for a while.
With Moats, Dupree and Chick now all at about 250#, (Dupree and Chick both lost 20 or so pounds in the off-season), it will be more difficult to be the type of traditional DE/OLB others and ourselves have employed in a 4-man front.
I would seriously consider Tuitt at DE/OLB in nickel with Hargraves on the field as well. IF Tuitt can 'push' the pocket back as Woodley used to, it prevents the QB from stepping up in the pocket which makes it easier for the OLB on the opposite side to reach the QB. (not to mention our two other interior DL)
While there may be some who disagree, our DL will be beaten to death with double team blocks and more likely to get injured going 3 on 2 for a full game.
Tuitt and Heyward are the only players with 4-front DE experience in college and have the requisite athleticism to ride outside on the offenses' right, IMO. BOTH of them are better athletes than Jones who is neither big, strong or fast.
