Veteran help isn't exactly the answer either. Galloway, Lloyd, Ocho...that's three seasons where we didn't have the right answer at outside wide receiver - although Lloyd was obviously far better than the other two, and plays the position adequately.
We've integrated 6 young players into our offense in the last several years (Gronk, Hernandez, Woodhead, Ridley, Vereen, Edelman) - so I think the notion that this offense is too complex for a rookie is not entirely accurate. It's too complicated for some rookies, but the right rookie makes an impact within 1-2 years. In some cases, a huge impact.
