Penning gives the Chargers a big-bodied, experienced option across the line. He does not need to win a glamour job to matter; he can cover guard or tackle and bring a physical edge to short-yardage packages. The opportunity is there if he can make his technique and discipline more dependable.
Strengths: Outstanding size, multispot experience and 33 career starts. He can offer legitimate emergency tackle or guard depth instead of being a developmental-only backup.
Weaknesses: His play has been uneven enough to prevent a settled starting role, and he must improve consistency, balance and discipline. The crowded line means he cannot rely on traits alone.
