This can put spikes in coverage if you play a 4-3. That's not a good situation. If you're going to play a 4-3 with only 1 real DT you'd be better having nink as the other and sheard be the OLB and put Hightower at silb or wilb.
Sheard, Nink, Easley, Jones
Hightower, Mayo, Collins
Add branch to that mix on 1st and 2nd downs
Not to mention we spend a lot of time in nickel then the question is who do we take off the field to put spikes on.
He can be a a back up and short yardage player but not much more.
