Philip Rivers heard the critics suggesting he's an old, rickety quarterback on the last limping leg of his NFL career who moves like a FedEx truck in a league of Corvettes. The 38-year-old knows all the talk about the 23 turnovers in Los Angeles last season, including 20 interceptions, too many of which were ugly heaves.

The criticism suggesting he's no longer an upper-echelon quarterback prickled Rivers' undercarriage at times.

"At times what may have aggravated me a little bit last year was [critics saying] that I couldn't play anymore," Rivers said Wednesday, via ESPN.
