plenty?
Calvin Johnson is arguably one, at 6'5" 236, vs. Aaron 6'1" 245.
Vincent Jackson is listed at 6'5', 230.
Plaxico Burress was listed at 6'5", 232.
Several WRs top Aaron in height but I am not aware of any at all that are listed at both a higher height and a higher weight.
Aaron would be one of the largest WRs in the NFL if he played there full time.
Ok true. I thought of those three guys off the top of my head, and there are other big receivers like Dwayne Bowe (6'2", 221), Anquan Boldin (6'1", 220), Andre Johnson (6'3", 220), Marques Colston (6'5", 225), Dez Bryant (6'2", 225), Larry Fitzgerald (6'3", 225), Brandon Marshall (6'4 1/2", 230), etc.
