Three years ago, it was unthinkable that the Chargers willfully would cut ties with quarterback Philip Rivers. But consecutive mediocre seasons, combined with the reality of new faces at head coach (Mike McCoy) and general manager (Tom Telesco), puts Rivers in a precarious position as he enters his 10th NFL season. U-T San Diego columnist Kevin Acee summed up the situation during a Wednesday appearance on NFL Network's "Path to the Draft." "No one will say it, but I think that 2013 is the final audition of Philip Rivers," Acee said. Acee bases his assumption on the Chargers'decision not to restructure Rivers' contract this offseason despite the team's tight salary-cap situation. Acee says the Chargers' choice to sit tight on Rivers "speaks volumes." Source: NFL.com
