Andre Johnson and Anquan Boldin aren't really underrated....they are rated exactly what they are, superstar WRs.
Former Steelers coach Bill Cowher recenty named Andre Johnson the #1 WR in the league today. he did leave off Anquan Boldin from his list, which was pretty fucking odd...
but yea, they aren't underrated, they just aren't that well known. perhaps because they stay out of the media or because they dont really come from teams with big cities...although Houston is pretty damm big..
Underrated WRs would be like Lance Moore, Steve Breaston, Kevin Walter, Dwayne Bowe....
