He’s a strong safety, a notch or two below the level of Bradley McDougald. If the price was right, and they were truly committed to ditching Earl Thomas, then maybe a McDougald FS/IIoka SS pairing could make sense.
Should probably go to the NFL Forum with this, unless the Seahawks show interest.
Edit - I guess he has played some FS in the last couple years. Similar to McDouglad, except a little bigger and slower.
