Yeah, that Brett Perriman take is ridiculous. It was in an SI article polling former wide-receivers about current wide receivers. If any receiver benefitted from a system it was Perriman with the Detroit Lions' spread offense. I think Herman Moore and Barry Sanders drew some defensive attention away from Perriman.
That SI article also had a comment from Ken Burrow - "Matt Jones is all sound, no picture". Weird that they would even comment on a player who's not in the league.
They picked Larry Fitzgerald as the best receiver in the league. He's 10th in yards this year and his longest gain is 27 yards.
