What benefits should we expect from the 3-4 switch?

Obviously we want the defense to be "better"......but we've had "better" defenses with the 4-3 as well. In fact, pretty much every defense in the history of defenses was better than what we saw last season.

More specifically, what benefits should we expect, from a schematic standpoint, by switching to the 3-4? Will our personnel be better suited for it? Will it hide weaknesses of some of the players that may otherwise be glaring in a 4-3? Will it lead to a better pass rush?

Would love to hear everyone's take on this.

It benefits the younger talent (Galette, Jordan, Hicks, and Wilson principally I think). It's somewhat at the cost of older players (Vlma and Smith principally) but I think we're all ready to move on from that era. So I think primarily, besides the energy the change will bring and the 3-4 blitzing defenses are just more fun to watch, it's about fitting the defense more towards the skillsets of our younger talent, instead of forcing them into somewhat awkward roles for the sake of declining veterans.
