The Chiefs basically gutted the defense by moving out 2 older players in Eric Berry and Justin Houston and trading away a player who likely would be a hard fit in Dee Ford by doing a 4-3 defense now. They have signed younger not acclaimed defensive players to man those spots in Tyrann Mathieu (safety) , Bashaud Breeland (CB) and Alex Okafer (DE). Those were the only real big free agents and Breeland is a risk one since he was hurt half of last season.
So I'd think they would draft defense and look at adding a CB or defensive line. But with Tyreek Hill's situation as them and the league wait on what comes next , the Chiefs may look at drafting a top WR if one falls to them. As someone joked in a pre-draft deal ...if you know your defense isn't gonna be there yet , just add more gasoline to that offense and Pat Mahomes.
