With these four holes, I'm most comfortable leaving DT un-addressed.
We were 11th in Rush Defense and 24th in Pass Defense. We were 32nd in Pass Offense.
We can improve our pass offense by drafting WR. We can improve our pass defense by drafting CB. Drafting MLB improves both. Drafting DT mainly improves rush defense. While a stud DT would provide a huge boost, I just don't see it as essential.
WR: Simpson & Wright
CB: Cook & Robinson
LB: Cole or Mitchell
DT: Guion & Evans
Of those four groups, I'm most ok with Guion & Evans "getting by" for one more year. I think WR comes next, with CB and MLB being "must-have".
Moreover, DT can be addressed in the later rounds. We can find less talented "high-motor" guy. That would not be ideal but I think a steady rotation at DT, keeping all three guys fresh, would be plenty, especially with an upgrade at MLB behind them.
