Aside from interior defensive line, this is likely the weakest position group on what is otherwise a strong defensive unit, barring inevitable injuries which have already knocked out a key contributor. In my opinion, when comparing them to the safeties around the league, the Chargers safeties just aren't very good. Jahleel Addae is much improved from his rookie year but he's still out of control and a liability in practice. Tre Boston is far and away the best against the pass but his tackling woes already showed up in week 1 of the preseason. No other safety to me should be on an NFL roster, save the rookies.
This is where we are, though. When a general manager that doesn't value a position that can be the wildcard of your defense, you end up with leftovers at the position. Speaking of week 1 in the preseason, we got a glimpse of 5th-round rookie Desmond King and his ball skills. His interception was a layup but it was good to see him chase down the receiver and poke the ball out. That's good play-speed. He doesn't have the most to prove by any means but if he can work himself into the rotation along with Boston as a deep safety the Chargers will be much improved on the back end. 4th round rookie Rayshawn Jenkins is a special-teamer until proven otherwise.
My only memory of Dexter McCoil from Sunday is coming up and missing a tackle. I imagine the coaches remember this as well and he won't be on the roster come September. Adrian Phillips at best should be on special teams. He's flashed but isn't anywhere near consistent enough to warrant a roster spot. When I say this I'm thinking in terms of playoff teams. These guys should not be on playoff rosters.
I expect Dwight Lowery to be phased out unless they carve a role out for him that doesn't involve anything over 7 yards. He had a chance to prove himself last year and failed. He's a fine 3rd safety but I don't see how you can be comfortable with him on the field in the 4th quarter needing a stop in coverage.
Even after getting a new contract, I think Addae has the most to prove. He played 8 games last year. Missed 3 games the year before. 5 the year prior. It's blind faith to assume he'll be healthy every game. As I mentioned, he has gotten better. Still a bit of a wrecking ball but he's borderline good against the run. He still gets turned around down the field in coverage, whether man or zone. He needs to improve there. 1 interception in 48 games just isn't acceptable.
We'd be crushing anyone else who had that stat line so I can't give him a pass. Never more than 4 passes broken up in a season, either. If Addae can build off of how he played the 2nd half of last year, he'll be fine. He needs to put a full season together and while he doesn't have to be a playmaker, he needs to have more of an impact on the game.
