Why Judge at WILL? Why not MIKE? I see they still have Woods, but they didn't bother playing him in '19, and Woods is getting old after so many years of not playing. Unless they have some star IMP MIKE, I'd put a good, cheap IMP at WILL, much like we did with Wilson.
With what I'm guessing they are paying Judge, you need him to be a high-impact high-value position.
Depending on the defensive scheme, WIL can be as high impact as MIKE. Heck, in his prime, Chip Cox was the high impact LB at SAM.
They could just as easily play Judge in the middle, but my guess is that with his cover skills and past success at WIL, that's where they will use him.
