Just looked at the Trent Green/Drew Brees breakdown from 2002-2005. Which was Green's top play and when Brees played in San Diego. Brees only played one game in 2001 and Green didn't have the best year either.
I uploaded Green's stats in Kansas City and Bree's stats in San Diego.
2002-2005 Per Game Averages for Green
1.4 TDS per game
.84 INTS per game
2002-2005 per Game Averages for Brees
1.36 TDS per game
.91 INTS per game
Just some food for thought.
