No. That was year 4.
Yr 1 didn't play (1 game). Year 2-3 not great. Again, barely over 3K passing yards and more int than TD.
Year 4 was his breakout year, followed by an ok year 5 where the Chargers were willing to let him walk.
He was not the Hall of Famer in SD that he became in NO. That is all I'm saying.
