I think lack of depth inside forced him there. Hopefully next season he’ll move back outside. Blitzing and containing was a strength of his. Most likely losing Deandre Johnson and possibly Kivon. Either way he would have opportunity there. Inside next year looks good between To’oto’to, Banks, Willis, Lewis. Can’t forget about Eason and French as well
The same can likely be said of LBs on the defensive side of the ball, too, though. If you aren't an EDGE LB or an elite 3-down MLB or WLB, you aren't going round 1, either.
With so many teams running 2 LB schemes (Nickel) as their base defense, anymore, the position is being phased out for LBs that can't either drop back in coverage (Deion Jones, Fred Warner) or rush the passer (Chandler Jones, Khalil Mack) at an elite level.
