The San Diego Chargers acquired veteran quarterback Billy Volek in a trade from the Tennessee Titans in exchange for a 2007 sixth-round draft choice. The draft choice could become a fifth-round choice if Volek participates in 50% of the team?s total offensive plays in ?06. ?We?re excited to add Billy Volek to strengthen our quarterback position,? said General Manager A.J. Smith. ?We?re always exploring ways to upgrade the talent on the Chargers. Billy brings talent and experience, and adds depth at that very critical position.? Volek, currently in his seventh NFL season, has started 10 games over the past three seasons. In those 10 starts, the 30-year old has thrown for 2,789 yards, the most passing yards by any quarterback in his first 10 starts dating back to 1970. In 24 regular-season games played, Volek has completed 312 of 517 pass attempts (.603) for 3,505 yards, 26 touchdowns, 13 interceptions and a quarterback rating of 86.9. He has not seen regular-season action thus far in ?06.
