I think it's a bad idea to carry six receivers.
I think we'll see something like this:
1.
Chaz Schilens
2. Johnny Lee Higgins
3. Darrius Heyward-Bey
4.
Javon Walker
5. Louis Murphy
Practice Squad: Watkins, Holland or Bayes.. who knows
Don't forget, Zach Miller gets a lot of receptions and we already have a DB, Justin Miller, returning kicks.
In terms of special teams, I'd prefer linebackers or defensive backs to fill these roles on the 53 man roster. (e.g. guys like Jerome Boyd, who I think could be a candidate for special teams gunner; maybe David Nixon or even Stryker Sulak)
