Every pundit I have heard has said he his the best rated WR prospect since AJG and Julio.
That's why busts are busts--they were expected to be good. Every pundit you've heard praise Watkins has been wrong a lot.
As you said; it's all opinion at this point and I could be wrong just as easily as you could.
And that is why this hobby is fun. None of us really have much of an idea but we all think we do...
