There are a lot of great WRs in the area of Harrison and Wayne and Brooks, etc throughout the NFL, especially if you go back to the Raymond Berry era. How about Rice and Taylor with the 49ers, just to name others.
Colts don't register on the scale compared to some other clubs, IMO. Outside of Harrison and Wayne, our WRs have been pretty bad. And don't forget that both Harrison and Wayne were first round draft choices, so there is a reason why they stand out.
Actually, East is correct because he said "at Pitt" which means when the Chargers played at Heinz Field. The Chargers won their last 2 away games against the Steelers.
