Fair enough, I can see the argument for Winston, RG3, Luck and Mariotta. I don't think they are quite as good as Watson, but that's just my opinion.
I think if you watched the Clem-OU Orange Bowl game this past season, it would be ignorant to say that Watson isn't clearly more talented than Mayfield.
I'll put it to you guys this way, I have two really good friends that are associated with Clemson University that I speak with on a daily/weekly basis -- one is an ex, and the other is Adam Humphries. Adam has caught passes from both Deshaun and Jameis, and played with both for at least a year. According to him, Deshaun has far more talent, but Winston is an absolute football genius. He says Jameis gets more out of the talent that he has than anyone he's ever known. I think it's an interesting conversation, and it will be cool to watch as things play out over the next few years.
