3. Jamal Williams
There are a few players that could be picked here. As mentioned, Lorenzo Neal absolutely has to be in the conversation as his run with the Chargers was some of the best play we have ever seen from a fullback. But with so much talent on the offensive side of the ball and no need for a fullback, he misses the cut.
You could also make the case for Shawne Merriman, who was an All-Pro in 2006 as one of the best pass rushers in the league. However, the 2022 Chargers already have a set of elite pass rushers and adding Merriman would not be maximizing his value.
Instead, the Chargers would benefit the most from getting another All-Pro defensive lineman in nose tackle Jamal Williams. Williams was a three-time Pro Bowler and two-time All-Pro with the Chargers as he was truly dominant from 2005 through 2007.
The Chargers' biggest issue last season was the run defense and while the team did address that in free agency this offseason, it would not be an issue at all with the addition of Williams. Williams is the definition of a run-stuffer and this version of him would make him one of the best in the league in 2022.
These three additions would make it really hard to beat the Chargers on any given Sunday. The offensive firepower would be way to overwhelming and the defense would be good enough to keep teams from keeping up.
