So I think the WOWY argument for Harrison is that (1) the Colts had great RANY/A numbers, (2) when Manning was still young and the team was not very good in ???01 and ???02, Harrison was a monster and one could argue he is responsible for dragging the Colts passing game to +0.7 RANY/A status, and (3) in ???07 and ???08, the passing attack fell off.
