Based on what you've seen of the defense so far this year, which positions

Olb still, although it's strange to see no apparent weaknesses in our defense as of now.

We'll need to reload in the secondary. Our d-line is going to be sick for years to come.

I wouldn't mind another tackle for depth

I think we should be looking for a new corner, Lewis and Greer have been ok but that position could use an upgrade.

Better db depth

corner, the safety opposite Vaccaro
We also need more depth on the line

I think 0-line will be the biggest priority in the offseason, however.
