As the 73 toll road turned into Interstate 5 and San Juan Capistrano and then San Clemente sped by unseen, Philip Rivers and Kellen Clemens watched tape of the Denver Broncos defense and then a little of the San Francisco 49ers defense.
It was the last Monday in August, the return leg of the first round trip for the Riversmobile, an SUV that has been gutted and turned into what the Chargers starting quarterback calls the “best QB room I’ve ever been in.”
The season opener against the Broncos was two weeks away, and there is only so much preseason tape can help.
