TD Epenesa has knocked Tua out with a rib injury a couple years ago and his hit on Tuna last year caused his first "spinal" injury.
Disrupt their WRs off the line, make Tuna hold it longer than he'd like.

Their OL isn't all that great, take advantage of that with some blitzing
A concussed Tua isn't very good, hit him early, hit him hard, hit him often. Make him put those falling lessons to work.
