I would agree......Forte and Warner win this one by far!!!! (not even close)!!!
Don't worry about wek one so let's take a look at the book (and not the cover): Forte > DWilliams and Warner >> Shaub so....
I would however take DWilliams and Shaub over T.Jones/Warner but it all depends. Warner will be great this year despite week 1, T.Jones was trash talked all last year and was awesome.....he has been trash talked this year as well and had a supreme week 1 (however, I am not buying it and feel he will falter soon and/or L.Washington starts taking over)....so it really depends on what T.Jones we get "this" year (the T.Jones everyone talks trash about or the T.Jones from week 1)
Then you have Shaub who had a poor outing week 1 but should get better (besides, the Jets D looked awesome) and D.Williams is great but look at the QB on that team and tell me how long Delhomme will last and while they are experimenting with him then the Defenses will just unload on Williams all day long!
Take the side with Warner in your original post but as far as the 2nd question goes it would depend on T.Jones and how he will do (maybe eye another week or 2 since week 1 was against a sorry D)
