1. Defensive tackle
You could stretch this out to the entire defensive line, as the team has one of the best defensive end combos in the entire league, but both Joey Bosa and Melvin Ingram are free agents after 2020. With that in mind, the Chargers very well could draft depth if there is a good fit in the later rounds.
The interior of the defensive line, however, is not going to be touched at all by the Chargers. It was a big need for the team last offseason and they attempted to address it then, so there is no need to address it now.
The Chargers selected Notre Dame’s Jerry Tillery in the first round last year and he hardly played in his rookie year, so the difference he makes if he is impactful will be like adding another first-round pick this year.
Right now, if the season started today, Tillery would likely be third on the depth chart.
Both Damion Square and Isaac Rochell are free agents but the team still has Brandon Mebane and Justin Jones to start. Plus, chances are that the Chargers will look to re-sign at least one of the defensive tackles for the depth purposes, and if not, can sign a cheap alternative in free agency.
There really is no reason for the Chargers to draft at defensive tackle as they are already deep at the position and have youth to get excited for in Tillery.
