What is the ideal size for LBs in the 3-4 on the college level?

We will be fine with size, especially now that Divinity is up to 240 and Alexander has gained some more weight. Problem is depth and experience

Depends on scheme. Bama seems to have 260lb LBs every year across the board

That's what we're missing is a nose

I would have to say around 230 grillnutts

Ideally, you want someone 6'3 or 6'4 and in the 240 range with really good feet. Von Miller is the prototype these days.

Your just getting guys like Arden Key standing up at more of an OLB role. You keep Herron, Bain, Loc, Clark, and Godchaux with their hands in the dirt. A true Nose Gaurd is all we really lack. I don't get all those saying we don't have the personnel, especially with Devin White now backing up Beckwith

Like Lester said you have to factor in height.

6' 240-245 is pretty solid. Anything past that and they'll probably be carrying more weight than they are made for and it could make them sluggish. (White doesn't count he's a freak)

While 6'3" 240 is pretty lean for a 3-4 ILB at that height someone could pack on 15-20 pounds and probably not be too sluggish.

You want to be as big as you can without losing speed and that's all it comes down to. The taller you are the more weight you can carry and still be efficient.

If we are running a 1-gap 3-4 like Denver runs (the scheme Aranda employed at Wisconsin) then it is an attacking scheme which allows the d-line to penetrate into the backfield and wreak havoc. This is in contrast to Bama's scheme, which requires the d-linemen to be responsible for 2 gaps and forces them to take on blockers to free up the LBers.
