Well considering he was #3 in the entire NFL in WR efficiency in 2015, not hard to come to that conclusion.
Antonio Brown is unquestionably the best WR in football. After that the clear #2 is Juilo Jones. Mike Evans to me would be #3. After that, it becomes arguable from there on down. Many would put OBJ there, and I wouldn't argue with it. If we are basing it on TALENT, then Watkins makes my top 5. If we are basing it on production, then I would put Jordy here.
Put a healthy Sammy on a team with a QB who can get him the ball, and his production would be on par with anyone in the NFL. But he had bad luck and had his foot injury suffer a set back impacting his season this year and he has spent half of all his games played catching passes from either Orton or EJ and the other from a run first QB on a run first team. But what he does with his targets is among the best in the NFL when healthy. He is an immense talent at WR, and to disregard it because of the offense he is in and his non career threatening foot injury is foolish IMO.
PS: If we get back to the original topic of this thread...
Without a shadow of a doubt, this board would be calling for the pitchforks if Sammy pulled an OBJ this week in both going to Florida and his poor performance on the field. They would have also tar and feathered him after his sideline tantrums this year too.
To further this point, if we had drafted OBJ instead of Sammy and OBJ was a Buffalo Bill and had similar production he has had in NY, then for the above mentioned things he would still be getting crushed here and ran out of town. But players on other teams always get a pass, while we tear down our best players here regularly.
