Middle LB's have been slim pickings lately in the draft. Seems like there are usually no "this guy will be great" in the ways that Ray Lewis, Patrick Willis.
Jack Campbell was picked in 2023 by the lions, and he's doing well but he's not amazing. At least not yet. Then you have to go back all the way to 2016 where Atlanta picked Deion Jones before a MLB in a 4-3 was selected in the first two rounds and was really good. (and for some odd reason he fell off after his rookie contract).
Just saying, it seems like MLB's have become an NFL position where no matter when the player is selected, they have to spend quite a few years before they become dependable. Arizona in the last 10 or so years have drafted 2 of em and neither worked out great.
But WILL's (which are also usually ILB's in a 3-4) seem to be a different story. Every draft theres a few that work out very well.
I have a sneaky suspicion that the standard 4-3 defense may adjust to big giant NT's for DT's, large DE's (not the 250 lb pass rushers but the 280+) and then the LB's can be smaller and faster, excelling in coverage then pass rush then run support vs MLB's being viewed as Run Support then coverage then pass rushing. Because with a very large Dline that can also pass rush, the opposing Oline won't make it to the 2nd level, free'ing up your smaller linebackers to wreak havoc and your strong safety supporting their run support.
Of course, if that does occur, then we'll see offenses slowly, but surely adjust to the 240+ lb runningbacks.
It's a slow game of paper rock scissors over years, but its paper rock scissors none the less.
