This question is asking my opinion, so I will give it to you. I have not seen many South Carolina wide receivers better than Alshon Jeffery. Jeffery is huge and has tremendous ability at the wide receiver position. I assumed that you were referring to South Carolina when you said Gamecocks. You could also be asking about Jacksonville State as they are also nicknamed the Gamecocks.
was is Mike Rozier?
Pfft... Hines Ward. What a dumb question...
The best wide receiver in the nfl is Andre Johnson.
Jerry Rice was and still is the best receiver ever
Currently Larry Fitzgerald is their best receiver.
Terrell Owens is a wide receiver. He is one of history's greatest receiver's. The gloves he wears are a type of wide receiver glove.
There are many good NFL players and teams, it is hard to say which one is the best wide receiver, as this is very hard to answer.
