Harper question in 3-4

I saw someone on twitter suggesting this, but he's too small. He did seem to be better in coverage this year playing zone.

He is our best tackler, IMO.

Now thats like saying you're the smartest person in a group of retards, but still.

Safeties in 3-4 need plenty of range. They are required to be part of the blitz disquise at the LOS and must retreat back into coverage if not blitzing. Is Harper good at this? I don't know. But I do know he would thrive in the blitzing aspect, but coverage skills and speed are a must for the Safeties.

Feel free to correct me if I'm wrong.
