Some of these lists are so ridiculous it hurts my head.
Calvin Johnson - absolute beast and monster for so many years. Freak with his height, weight and speed. Unfortunately went to a team that wasn't very good and took a beating over the years and had to retire because he was getting cut up.
Terrell Owens. Great WR for almost every team he played for and if he didn't have an attitude and ego he could have been probably the best. Ravens great TO.
Larry Fitzgerald. Longevity and amazing receiver overall. Unfortunately again, one of the best we may be able to witness that just ended up on a team for his career that just couldn't pull it out.
Antonio Brown. Selected in the 6th round and not much expected out of him. 3x all pro and yards leader in 2014. Has turned into one of the best WRs we have seen in the past 10 years. Has so much upside and continues to produce at an alarming rate.
Julio Jones. 2x all pro in the past 2 seasons and receiving yards leader in 2015. In the league for 6 years and already almost has the same amount of yards as AB. These two are debatable.
Steve Smith Sr. Longevity gets him above Andre Johnson and thats the only reason. Smaller but very aggressive and had a great 2005/2008 season. Only reason I do not have him higher is because I did not include his returning stats on ST. If this was included into the argument I would have him higher. I am only going off pass catching receiver.
Andre Johnson. Again another WR who was just unlucky to land on a bad team for a majority of their career. Would have been amazing to watch him play for a bigger club when he first came into the league.
