Yes. Brady is better with all-world receivers.
We love to lok back with fondness at the 03-04 champions. I know I do. But I remember more than one game that was won with no TDs at all ! Wasn't the Tedy TD the only one scored in the snowball toss, for example ?
The D was hot, so we might not remember all the low scoring that was going on. I prefered it, because it was winning football - but the offense was not clicking like it is now. What it DID do, though, was click at the end of the game when we needed it... but does Welker/Moss prevent us from second half scoring ? I say no.
