The lessons learned between the end of Preseason Game No. 3 and the end of Preseason Game No. 4 were not drastic or dramatic.
The blowout loss to the San Francisco 49ers did not tell fans too many new things. We still know the offense will try to execute at a fast tempo, the play calling will be balanced and the backups are a concern. Fans knew those things following the win over the Arizona Cardinals.
Most of what was learned was from management and coaching and how new general manager Tom Telesco and new head coach Mike McCoy plan on running the San Diego Chargers this year and in years to come.
