Three keys to Chargers defense being dominant

Linebackers
The Chargers’ defense has not been known to get consistent play out of their linebacker group in recent years but with the addition of Davis, there could be some hope that he brings the playoff pedigree he earned in Carolina. There is a question as to how much the 13-year veteran has left in the tank, but it should be enough for the Chargers to bring him on a two-year deal.
They also drafted Denzel Perryman in the second round of the 2015 draft and that hasn’t turned out in favor of the team as he hasn’t been able to stay on the field and his inconsistent play throughout his career.
It remains to be seen who elevates the linebacker spot for the defense this season and it’s crucial because this is the only “hole” they seem to have on defense.
With the talent they have up front on the defensive line and in their defensive backfield, they’re able to mask that lone hole on their defense, but if they truly want to be dominant it would be wise for the team to find their key cog at that spot.
