Brown was a premier receiver from 1993-2002. He started to taper off in 2003 and only had 4 starts after the passing game opened up in 2004. Harrison had 67 starts during and after the 2004 season.
Harrisons stats didn't improve in those years, but its possible that they would have declined without the rule changes.
Add the 4500 return yards and the difference in quarterbacks between the two, and it is an easy choice to put Brown in before Harrison.
