Hpw do you know that McVay gives the DC a choice to change the defense?
I don't.
You & I know that McVay prefers a 34 defense. I would guess he is still drooling over Vic Fangio who is one of the best 34 D DC I know myself. Who knows Mcvay still might have a chance to bring him here with Staley as his assistant. But Snead will have to get serious & draft a few healthy standup 34 OLB'ers with the talent to entice Vic. Vic is sure doing a good job in Philly.
When I review this current & future MR53 plus IR & PS. It's clearly evident that this DL unit is full of good young talent. The OLB unit has very few true 34 OLB'ers. Most of the OLB'ers in the unit are true 43 DE's.
At this point in time, the 32 yr old Floyd is the only bonified 34 Defensive OLB'er on this team. Hopefully 7th rd 2022 draft selection Daniel Hardy possibly might morph into a stand-up OLB'er but he was a pure 3 pt hand-in dirt DE pass rusher in college, not an OLB'er.
Because McVay continues week after week unable to enter an NFL gm with the appropriate amount of NFL skilled OLB'ers in his desired 34 D. Clearly evidenced by the last few seasons Snead has lost the ability with his scouting team to locate & get in NFL grade 34 OLB'ers to the field so his DC can use them.
