Rivers was projected to be an early first-round pick in the 2004 NFL Draft. However, despite Rivers's record of success in college and remarkable accuracy (72% completion percentage for his senior season), questions about his lack of arm strength and his unorthodox side-arm throwing motion were concerns for some NFL GMs. The pre-draft consensus was that Rivers could be selected by the Pittsburgh Steelers with the 11th pick. The San Diego Chargers coveted Eli Manning and wanted to select him with their first round pick, which was also the first overall pick of the draft. However, after Eli Manning indicated before the draft that he would not sign with them. Rivers was their first alternative because the Chargers head coach at the time, Marty Schottenheimer, had coached him at the Senior Bowl and he liked what he saw. The Chargers agreed to a draft day deal with the New York Giants. San Diego selected Manning first, then traded him to New York for Rivers, taken by the Giants fourth, plus draft picks later used by the Chargers on future Pro Bowlers Shawne Merriman and Nate Kaeding.
